Do not reuse tracking ids after a no-touch event

The fingers going away are important in the matching algorithm,
to correctly detect new fingers when placed close to a finger
in the process of leaving the surface. However, once a no-touch
has been confirmed, the tracking id should not be reused, should
a new finger appear close to the removal point.

This patch clears the tracking id of all removed or no-touch state
fingers, thereby reducing accidental jumps on touch to a minimum.
