Fix missing Note access checks in by moving Note#search to updated NoteFinder

## Which fixes are in this MR?

⚠ - Potentially untested  
💣 - No test coverage  
🚥 - Test coverage of some sort exists (a test failed when error raised)  
🚦 - Test coverage of return value (a test failed when nil used)  
✅ - Permissions check tested

### Note lookup without access check

- [x] ✅ app/finders/notes_finder.rb:13 :download_code check
- [x] ✅ app/finders/notes_finder.rb:19 `SnippetsFinder`
- [x] ✅ app/models/note.rb:121 [`Issue#visible_to_user`]
- [x] ✅ lib/gitlab/project_search_results.rb:113
  - This is the only use of `app/models/note.rb:121` above, but importantly has no access checks at all. This means it leaks MR comments and snippets when those features are `team-only` in addition to the issue comments which would be fixed by `app/models/note.rb:121`.
  - It is only called from SearchController where `can?(current_user, :download_code, @project)` is checked, so commit comments are not leaked.

### Previous discussions
- [x] https://dev.gitlab.org/gitlab/gitlabhq/merge_requests/2024/diffs#b915c5267a63628b0bafd23d37792ae73ceae272_13_13 `: download_code` check on commit
- [x] https://dev.gitlab.org/gitlab/gitlabhq/merge_requests/2024/diffs#b915c5267a63628b0bafd23d37792ae73ceae272_19_19 `SnippetsFinder` should be used
  - `SnippetsFinder` should check if the snippets feature is enabled -> https://gitlab.com/gitlab-org/gitlab-ce/issues/25223

###  Acceptance criteria met?
- [x] Tests added for new code
- [x] TODO comments removed
- [x] Squashed and removed skipped tests
- [x] Changelog entry
- [ ] State Gitlab versions affected and issue severity in description
- [ ] Create technical debt issue for NotesFinder.
  - Either split into `NotesFinder::ForTarget` and `NotesFinder::Search` or consider object per notable type such as `NotesFinder::OnIssue`. For the first option could create `NotesFinder::Base` which is either inherited from or which can be included in the other two.
  - Avoid case statement anti-pattern in this finder with use of `NotesFinder::OnCommit` etc. Consider something on the finder for this? `Model.finder(user, project)`
  - Move `inc_author` to the controller, and implement `related_notes` to replace `non_diff_notes`/`mr_and_commit_notes`

Fix Crontab typo for PruneOldEventsWorker to run 4x/day instead of 60x/hour

Correct autocomplete for values with special characters

This adds a check for any special chars in any value passed to the `DefaultOptions.beforeInsert` callback function. If special chars are found and `skipSpecialCharTest` option is `false`, it will wrap the value in quotation marks.

This fixed autocompleting `~customer+` instead of `~"customer+"`.

fix display hook error message

## What does this MR do?

Fix hook error message display.  

## Are there points in the code the reviewer needs to double check?

Probably Hook will return the plain multi line text.  It is better `pre` tag than `h4`.  
I thought of another good looking display, but I did not come up with it. 😓 

## Why was this MR needed?

When the hook returns an STDERR, "Merge in progress" button spinning forever. Due to javascript's error.  

## Screenshots (if relevant)

When update hook returns an error like

```
XXXXXXXX

YYYYYYYY
ZZZZZZZZ
```

Fix compatibility with Internet Explorer 11 for merge requests

## What does this MR do?
This merge request restores the compatibility with Internet Explorer 11.

## Are there points in the code the reviewer needs to double check?
No.

## Why was this MR needed?
Commit ca3c0c6c introduced an incompatibility with Internet Explorer 11. On all merge requests in all projects the 'Changes' tab does not display the changes in IE11 but instead fails with 'Something went wrong on our end'. The reason ist, that this code snipped produces different results on Firefox and Internet Explorer 11:

```
var element = document.createElement('a');
element.href = '/some/absolute/url';
alert(element.pathname);
```

With Internet Explorer 11 the alert will print a relative path, whereas with Firefox the alert will print an absolute path. For GitLab this meant that a wrong AJAX URL was composed which resulted in a 404.

## Screenshots (if relevant)
None.

Pipelines tabs

## What does this MR do?
Changes the URL when the builds tab is clicked making it possible to be shared.

1. Adds a standard way to handle linked tabs:
    *   This behaviour is already present in the merge requests, commit and user `show` page. 
    *    This MR introduces a reusable way to accomplish this behaviour for pages with static content.

2. Adds test:
    *   For the linked tabs reusable class
    *  For the pipelines tabs

## Why was this MR needed?
To allow having a sharable URL that represented the opened tab

Resolve "Highlighting lines is broken"

Add line highlighting back to diff view.  This was working in the MR "changes" tab, but not on a commit page such as https://gitlab.com/winniehell/reproduction-area/commit/9101e66f5761929002956e0f2dd65d7f8643903d

~~This MR also fixes the `scrollToElement` method in `MergeRequestTabs` to account for the extra height of the tab links which are now fixed in place once they are scrolled to the top of the screen.~~ (removed in favor of !7051)

This MR also refactors much of the `Diff` and `MergeRequestTabs` classes to es6 syntax in an effort to increase readability.

Check out both MR "change" tabs and commit diff pages and ensure that line highlighting works and that loading a page with one of these permalink hashes correctly highlights and scrolls to the line.

Ensure I didn't break anything in the transition to es6 syntax.  Check the functionality of the tabs on MR pages, as well as diff page interactivity (unfolding hidden lines in diff files, adding comments to diffs, etc).  I have checked these myself, but another set of eyes would be a good idea.
