Prevent bouncer from showing during unlock animation

There is a delay in keyguard showing state change when unlocking via
FPS. When a swipe down occurs during this change, the bouncer would
flicker on screen. Prevent bouncer showing if keyguard is going away.

Fixes: 284454840
Test: atest StatusBarKeyguardViewManagerTest
Test: manual, swipe down after unlock with FPS
