Fix and test user contributed projects.

Fixes #2077.

See merge request !1606

Include number of affected people in all/group mention autocomplete item.

As mentioned in #2054.

To minimize misuse of all/group mentions, the autocomplete title includes the number of members this mention will notify, so users will be more considerate what groups they mention.

Example:

at-all "**all** All Project and Group Members (12)"

at-gitlab "**gitlab** GitLab (12)"

Introduce shortcuts for routing helpers

Filter icons look like proper buttons

The filter icons (Push events, Merge events, Comments, Team) now have a border
that signifies they can be pushed. This not only keeps it in line with the rest
of the application buttons, but it makes it more obvious, especially for the
Merge events button with a checkbox icon.

Fixes #1993

[ci skip]

Make test element selection more specific to fix constantly failing test.

Fixes #2051.

The problem was that there were two `.note-text` elements matching `.files [id^=diff]:nth-child(2) .note-text`, one for the new comment, and one for the (currently hidden) new comment form. The latter one was selected but currently invisible, triggering the following error in poltergeist:

> The element you are trying to interact with is either not part of the DOM, or is not currently visible on the page (perhaps display: none is set). It's possible the element has been replaced by another element and you meant to interact with the new element. If so you need to do a new 'find' in order to get a reference to the new element.

This caused the test to fail.
