Fix a 500 error viewing an MR with a deleted source project

## What does this MR do?

Allows merged MRs to be shown without any 500 errors if the source project is removed

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

https://gitlab.com/gitlab-org/gitlab-ce/commit/31c37c6c38258684fc92e0d91119c33872e39034 fixed this for closed MRs only. I had trouble understanding the introduced helper and logic, so reverted it and keyed everything on the existence of the source project or branch directly.

commits.json returns a 500 error for a closed or merged MR; the approach taken in the above MR was to hide the commits... tab, so I've run with that.

For merged MRs, the commits (but not the pipeline data) are in the target project, so we *could* do better, but it's a fairly nasty intervention to make it happen.

## Why was this MR needed?

Viewing merged MRs should work even if the fork they came from has been deleted or unlinked.

## Screenshots (if relevant)

Update duration at the end of pipeline

## What does this MR do?
Moves duration calculation to be done only once at the end of pipeline processing.
Currently this is done every one build.

## Why was this MR needed?

Keep around commits only on pipeline create

## What does this MR do?

Fix name of feature that restricts access to builds traces

## What does this MR do?

Also, as part of this fix, I removed applications of `-webkit-overflow-scrolling: auto` in two other places where they're no longer needed. One was the file-holder. I made sure I could reproduce the behavior this was intended to fix, and then made sure this MR still fixed it. 

Here's the errant behavior:

Wait for ajax for every merge request spinach test

## What does this MR do?

* removes duplicate `WaitForAjax` module
* ensure we run `wait_for_ajax`after each MR spinach tests

## Why was this MR needed?

Because when visit MR page we do ajax call to check CI status. When testing this page with spinach and JS driver we got random failing tests. It happens because of race condition db cleaner drop data before ajax call finished. So we make sure that every MR spinach scenario with js driver waits for ajax before running next scenario

Delete dynamic environments

- Adds "close environment" action to a merge request
- Adds tabs to environments list
- Adds close button to each environment row in environments list
- Replaces Destroy button with Close button inside an environment
- Adds close button to builds list inside an environment

In order to enable stopping environments a valid `.gitlab-ci.yml` syntax has to be used:

```
review:
  environment:
    name: review/$app
    on_stop: stop_review

stop_review:
  script: echo Delete My App
  when: manual
  environment:
    name: review/$app
    action: stop
```

This MR requires that `stop_review` has to have: `when`, `environment:name` and `environment:action` defined.
The next MR after this one will verify that and enforce that these settings are configured.

It will also implicitly configure these settings, making it possible to define it like this:

```
review:
  environment:
    name: review/$app
    on_stop: stop_review

stop_review:
  script: echo Delete My App
```

LDAP login style fixups

## What does this MR do?
* Addresses regression found here: https://gitlab.com/gitlab-org/gitlab-ce/issues/23435
* Adds border radius to left/right tabs

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

So you know what you're seeing, there are three types of fixes going on here: 

1. Template syntax errors that were displaying template-like language in the DOM (specifically with ldap and crowd username labels
2. Aesthetic problems in tabs that arise with more than 2 tabs
3. LDAP and crowd tab functionality. I had to move each panel into its own login box, to ensure that each panel's id synced with its associated tab's href, and that each panel was at an equal depth within the DOM. I assumed bootstrap tabs would look deeper into the login-box to find panels that matched the tabs. This is not true. The reason I didn't catch this is that in development I was just manually changing template flags to force rendering. I didn't realize I could enable ldap in CE within the gitlab.yml file 🤦
