UserAwareBiometricScheduler lifecycle fix.
Fixed an issue where UserAwareBiometricScheduler queue would get stuck
indefinitely(causing face/fingerprint to fail until reboot).
Testing steps to reproduce
Setup.
* Have multiple users with multipler biometrics.
1. Add a property in a biometric HAL(Call it biometric A) to hang on auth operation
2. Set property to hang when authenticating(biometric A).
3. Unlock device with alternative biometric(biometric B)/pin/pattern/pass
4. Unset property to stop biometric(biometric A) from hanging
5. Rinse and repeat 1-4 until a hang occurs
