Fix gitlab rake:import:repos task for 9.5.x

See merge request gitlab-org/gitlab-ce!14639

This backports !14597 for the 9.5.x branch.

Because of a change in GitLab 9.5.4 to prevent users from assuming control of
a repository already on disk, the import task broke. Imports would fail with
the message, "There is already a repository with that name on disk".

This change skips the validation when the import is done from the
command-line.

Closes #37682

Fix MR widget with ready to merge buttons/controls at mobile breakpoint

Closes #37259

See merge request gitlab-org/gitlab-ce!14242

If the ref doesn't exist, and the source branch is deleted, we can't get it back
easily. Previously, we ignored this error by shelling out, so replicate that
behaviour.

Fix: GPG tmp dir removal race condition

Ignore any errors when removing the tmp directory, as we may run into a
race condition:
The `gpg-agent` agent process may clean up some files as well while
`FileUtils.remove_entry` is iterating the directory and removing all its
contained files and directories recursively, which could raise an error.

Closes #36998
