To do so, many tests directly read and write references via the filesystem, assuming that we always use loose and/or packed references. While this is true now, it'll change with the introduction of the reftable backend. Convert those tests to use git-update-ref(1) and git-show-ref(1) where possible. As some tests exercise behaviour with broken references and neither of those tools actually allows writing or reading broken references, this commit doesn't adjust all tests.
