rebase: remove now unnecessary logic to allow empty commit when branch changes

This was a workaround for a bug in the empty commit check in repo.commit(),
where the parent branch name was incorrectly compared with the wdir branch name
instead of the branch name passed via `extra`. The bug was fixed in D8724.

The workaround was introduced in b2415e94b2f5.
