This commit attempts to change default user search scope if otp_user_id
session variable has been set. If it is present, it means that user has
2FA enabled, and has already been verified with login and password. In
this case we should look for user with otp_user_id first, before picking
it up by login.

Closes #14961

This also contains specs for a bug described in #14900

Only update main language if it is not already set

Related to gitlab-org/gitlab-ce#14937 (but does not fully fix) This is a temporary fix so performance isn't affected so much. 

cc @yorickpeterse @ayufan how does this look?

Update coveralls from 0.8.9 to 0.8.13 and simplecov from 0.10.0 to 0.11.2

This removes a few dependencies! It was also rude to be using coveralls
0.8.9, considering 0.8.12 introduced support for GitLab CI :) Also
paves the way for updating mime-types to 3.0.

Unblocks user when active_directory is disabled and it can be found

We implemented a specific block state to handle user blocking that originates from LDAP filtering rules / directory state in !2242. 

That introduced a regression in LDAP authentication when Active Directory support was disabled. You could have a scenario where the user would not be temporarily found (like a filtering rule), that would mark the user as `ldap_blocked`, but will never unblock it automatically when that state changed.
