ProtectedApps: add up navigation and fix action bar icons

 * ProtectedApps has up navigation, but the lock pattern has not.
   I catch myself many times when trying to press the up arrow and
   noticing later on, that it is not there.

 * the drawable used as action bar icon is not white, tint it white
   and use it instead.
