tests: missing refs/ in bare repositories (go-gitea#28844)

AdamMajer · GiteaBot · commit bb3cc1199386 · 2024-01-19T07:12:32.000Z
Git 2.43.0 will not detect a git repository as valid without refs/
subdirectory present. `git gc` cleans this up and puts it in
packed-refs. We must keep refs/ non-empty.
