Followup to r1603388: Fix ruby bindings tests for the new commit_finalizing notification.

* subversion/bindings/swig/ruby/test/test_client.rb:
  (assert_mkdir_with_multiple_paths, test_mkdir_p): Ignore notifications
    of the type Svn::Wc::NOTIFY_COMMIT_FINALIZING when producing the array
    of notifications to assert on.
  (test_copy, test_move, test_move_force): Expect the notification on '.' for
    the commit finalization, being careful to not expand the '.' path.
