[PATCH 5/9] tests: use --create-reflog option to git update-ref

[David Turner <dturner@twopensource.com>]

Instead of manually precreating reflogs by writing files, use
update-ref --create-reflog to create the reflogs at the same time
we first create the ref.

In one case, we need an entirely empty reflog, so we do a no-op
update-ref with --create-reflog and then expire the reflog.

This makes it slighly easier to test alternate ref backends.
