Some of our tests fail if the gitlab-org/gitlab-test repo changes
For example: https://gitlab.com/gitlab-org/gitlab-ee/-/jobs/47732668
In spec/requests/api/tags_spec.rb we falsely assume that new tags cannot be added to the gitlab.com/gitlab-org/gitlab-test repository.
I caused that failure by pushing a tag to gitlab-test. I pushed that tag to fix another broken test in Gitaly, that assumed the master branch wouldn't change.
I think we can say that some of our tests that rely on gitlab-test are too prone to breakage. This issue is to discuss what we are going to do about that.
