To restore all refs from a bundle, we need to use the --mirror option to
ensure that all refs are properly restored. Without this, refs such as
`refs/merge-requests/X` and `refs/keep-around/Y` would be omitted, which
exposed a bug as described in https://gitlab.com/gitlab-org/gitlab-ce/issues/38319#note_41648608.

Closes #38352
