PTFakeTouch ERROR! pointId all used after moving application into background

[Vladimir (Alkenso)]

Steps to reproduce

1. Run async loop with generating synthetic tap every second
2. Lock iPhone (press side button)
3. Unlock iPhone
   ER: taps continue to be performed
   AR: error "PTFakeTouch ERROR! pointId all used"

I've researched the issue a bit. After locking the iPhone all touches in touchAry have phase 'UITouchPhaseCancelled'

Found solution: in + (NSInteger)getAvailablePointId treat touch with phase UITouchPhaseCancelled as available (as Ended/Stationary are)
