Fixed extra margin when the merge request tabs are affixed

This was caused by some weird padding that was on the container & then
not correctly removed.

The fix involved removing the container from inside the tabs holder div
& then adding the widths through CSS depending on if fixed & whether the
parent is limited width or not.

In reality out container classes need to be fixed as it is getting pretty un-managable at the moment this should of been an easy fix, but in reality turned into something much harder.

Closes #26853

When there was no project, no search, and no current user or author
param, the AutocompleteController would call `#uniq!` on a relation
instead of an array. This performed the less-efficient `SELECT DISTINCT`
when it wasn't even needed (because the query wouldn't return duplicates
anyway - duplicates were only added by putting a user on top of the
list).
