Disable bypass and bouncer delay when no face auth

KeyguardUpdateMonitor#isUnlockWithFacePossible was returning true
when the user had disabled face unlock.

This was causing bypass to still be enabled (hiding all notifications)
and bouncer was also being delayed, even though we were not scanning.

Fixes: 134977472
Test: auth with bypass (toggling face auth setting on/off)
Test: auth without bypass (toggling face auth setting on/off)
