MODE_SHOW_BOUNCER - Make sure bouncer shows

On AOD, multiple failed attempts to unlock via fingerprint should
display the bouncer. Add a condition to the panel expansion that will
prevent the bouncer from showing and then immediately hiding.

Separately, reset() the BiometricUnlockController state after the
bouncer has been dismissed. This fixes an issue when the user swiped
back after the bouncer prompts.
