[PATCH] t5543, atomic pushes: test deleting and renaming branches

[Stefan Beller <sbeller@google.com>]

Add more test coverage to the atomic push option. It turns out there is a
breakage when renaming branches within an atomic push. The breakage occurs
because it cannot lock the refs v/v as well as x.
