Double Tap Gesture depends on touch-action of previous touch sequence.

This aligns chromium's double tap behavior with response to touch action
more closely with IE's behavior.

This required switching to resetting the touch action on the end of a
touch sequence instead of the beginning, to avoid the possibility of
resetting twice.
