WAKE_AND_UNLOCK when FP is auth'd while animating screen off

Device was previously running MODE_ONLY_WAKE, so the user
would instead see an unlocked lock screen when authenticating
while the screen off animation was running.

We also need to make sure the pendingLock (from goingToSleep)
is reset to false, because one we start waking up from the
biometric unlock, onStartedWakingUp is called and will attempt
to handle any pending locks. Therefore, onKeyguardDone, let's
remove the pending lock so that user doesn't get put back on the
locked lock screen right after authenticating while the device
was going to sleep.
