Add IntentFilter auto verification - part 11

- tune Intent resolution candidates filtering: add also the undefinedList
  into the results at first so that when you install an App which is not
  verified (after installing a verified App) you will still have the
  Disambiguation Dialog prompted to the User.

See bug #19628271
