[PATCH 3/3] rebase: finish_rebase() in noop rebase

[Ramkumar Ramachandra <artagnon@gmail.com>]

In the following case

  $ git rebase master
  Current branch autostash-fix is up to date.

the autostash is not applied automatically, because this codepath
forgets to call finish_rebase().  Fix this.  Also add a test to guard
against regressions.
