Fix sorting issues/mrs by votes on the groups page

Closes #14394 

The `non_archived` scope applied here https://gitlab.com/gitlab-org/gitlab-ce/blob/master/app/controllers/concerns/issues_action.rb#L5 overrides the previous `ORDER BY` applied inside the IssuesFinder, with the default scope of the Project model, resulting in SQL errors.

```ruby
Issue.reorder(created_at: :desc).joins(:project).to_sql
=> "SELECT issues.* 
    FROM issues INNER JOIN projects ON projects.id = issues.project_id
    ORDER BY issues.created_at DESC"

Issue.reorder(created_at: :desc).joins(:project).merge(Project.non_archived).to_sql
=> "SELECT issues.* 
    FROM issues INNER JOIN projects ON projects.id = issues.project_id 
    WHERE projects.archived = 'f'
    ORDER BY projects.id DESC"

Issue.reorder(created_at: :desc).joins(:project).merge(Project.non_archived.only(:where)).to_sql
=> "SELECT issues.* 
    FROM issues INNER JOIN projects ON projects.id = issues.project_id 
    WHERE projects.archived = 'f'
    ORDER BY issues.created_at DESC"
```

Fixes last remaining lints and enables scss-lint test for GitLab CI.

With this, builds will now fail if they break the SCSS style guide (at least, the parts enabled by the linter).

Discussed in #14299.

With this, builds will now fail if they break the SCSS style guide (at
least, the parts enabled by the linter).

Discussed in #14299.

Disabled SelectorFormat rule for SCSS Lint in order to get the Rake
task passing sooner.

SelectorFormat enforces that CSS classes and IDs use lowercase
hyphenated style, `like-this`, but a not-insignificant amount of
selectors in the codebase are `like_this`.

Fixing the selectors that break this rule would require changing HTML
as well, and potentially break JavaScript hooks, among other things. So
I decided to disable this rule for the time being, hopefully making it
easier to fix all the remaining warnings SCSS Lint is giving by removing
the most problematic rule.

Discussed in #14299.
