branch.c: use ref transaction for all ref updates
Change create_branch to use a ref transaction when creating the new branch.
This also fixes a race condition in the old code where two concurrent
create_branch could race since the lock_any_ref_for_update/write_ref_sha1
did not protect against the ref already existing. I.e. one thread could end up
overwriting a branch even if the forcing flag is false.
