Update lock icon view when biometrics cleared
To ensure when face auth is the only biometric
enrolled, that the unlocked icon immediately
becomes the locked icon on screen off (when
biometrics authentication states are cleared).
Also add the unlocked => locked icon transition
so there isn't a jump-cut animation when
AoD is enabled and the unlocked icon transitions
to the locked icon.
