I took a look at this. It turns out to be rather annoying, because we
can't just restore $missing. The earlier tests may have deleted other
random objects (like $recoverable) depending on whether or not they
actually failed.

So I'm inclined to leave it (we do confirm with the rev-parse call at
the end of the setup that our packed-refs file is working) unless you
feel strongly. If you do, I'd rather go the route of sticking each
corruption in its own separate sub-repo.
