Fixed an issue where the phone would be stuck pulseExpanding

During long drags, in combination with face unlock / bypass
the phone could get stuck pulseExpanding, especially when
the screen was turned off. We now give the pulse expandhelper
the touch if it is currently handling the pulse to gracefully
reset.

Test: expand with a long pulse with bypass, turn off screen, observe not stuck
