Close "Protected apps" activity during power cycle

Protected apps activity in Settings is accessed after entering
correct pattern. If user turns off/on the phone while Protected
apps is in foreground, the user must enter pattern again before
using the Protected apps.

Added code in onPause method to close the Protected apps activity
if the user has already been authorized and there is no screen
orientation change.
