Award Emoji: fix for merge requests

Closes #3597

See merge request !1865

[ci skip]

This reverts commit 240fcb40, reversing
changes made to 115bbd8a.

These two lines were removed from CE but need to stay in EE. This revert
ensures that we're up-to-date with the CE upstream but leaves the
required lines intact.

Remove accidentally added line.

Improve performance of user profiles, finding groups, and finding projects

This MR improves the following:

* Rendering of profile pages and Atom feeds
* Finding groups (using GroupsFinder & friends)
* Finding projects (using ProjectsFinder & friends)

Initially this MR was intended to only improve rendering of Atom feeds, but over time other fixes were introduced as well as the same code was the cause of all these problems.
