Don't cancel injected event when mouse event arrives

Currently, MotionEventInjector would cancel any injected gesture when
any MotionEvent arrives. For user using an external device to control
the pointer movement, it's almost impossible to perform the gestures.
Any slightly unintended movement results in the cancellation of the
gesture.

However, if MotionEventInjector keeps sending mouse movement events
when gesture is performing, dispatch logic would be confused and it
causes the gesture malfunction. Therefore, ignore movement events
from mouse when there is an ongoing gesture since click event from
mouse should be intended.
