Fix warning when trying to clone repo that already existed

What does this MR do?

This repo skips cloning the --bare repo for tests if it already existed

Why was this MR needed?

This takes care of the warning mentioned by @nick.thomas in #30284 (closed)

• All builds are passing

@nick.thomas I still had this prepared before I had to log off yesterday, do we want it in as well?

Seems to be affected by #30236 (closed)

@reprazent looks like a good addition!

Failing spec: https://gitlab.com/gitlab-org/gitlab-ce/builds/13385217 - maybe you just need to rebase?

@nick.thomas I implemented @rymai's suggestion from https://gitlab.com/gitlab-org/gitlab-ce/issues/30236#note_26522204 if specs succeed now I'll cherry-pick that into a separate merge request.
