Before this it would fail because git hooks automatically prepend
things to the path, which can lead the wrong Ruby version to be called
in which dependencies are not installed.

To make sure that this is correct, the forked_merge_requests commented
out test that depends on this change was uncommented.

For that test to pass, it is also necessary to setup the mock server
on port 3001 under test_env.rb.

Fix for #8271: Correctly restore empty repositories.

If a project is being restored, but there is no bundle file, the project was
empty when it was backed up.  In this case, just use git init --base to create a
new bare repository.

RAM Requirements update

512MB of RAM is not enough to install using omnibus-gitlab.

Installation will fail in very random places.

Manual installation might also fail with this low amount of RAM.

Performance improvements

Push 1k commits cause 1k sql queries to collect commit author. But this variable was used only in 20 commits (from 1000).
So we did 980 sql queries without using it. This MR fixes it.

In e23a26ae (and later 1bc99369) the API for Gitlab::LDAP::Adapter was
changed. I assume this rake task was an oversight in the refactoring of
the changed class.

While being on it, I noticed that already blocked users cannot be
blocked again.
