Re: [PATCH 4/5] refs.c: update rename_ref to use a transaction

Change refs.c to use a single transaction to copy/rename both the refs and

Yay!

            Since we are no longer using rename() to move the reflog file
we no longer need to disallow rename_ref for refs with a symlink for its
reflog so we can remove that test from the testsuite.

It's generally better to update the testsuite with the new expected
behavior instead. :)
