Perform double tap toggle on ACTION_UP.

Currently, the double tap event is processed on the initial ACTION_DOWN
of the second tap. This conflicts with potential drag reposition events
that may follow, causing the size change to be reverted when the drag
ends.

This CL has the double tap resize occur on ACTION_UP instead, and only
if there isn't a drag event being handled.
