Sending interaction end event at the end of a drag.
1. In explore-by-touch when the user slides two fingers in the same
direction we consider it a drag gesture. We merge the pointers into
one and deliver a touch event. When one of the pointers goes up
we were transitioning into touch exploring state. This means that
were transitioning to another state in the middle of a gesture which
creates complications and leads for interaction end event not being
sent.
This change transitions out of dragging state when all pointers go up
- simple and all events are properly sent. Consequentially, staring a
drag the user has to lift all pointers to touch explore. Since usually
users either drags or touch explores this seems the simplest and
*least risky* fix.
