[PATCH] Do sent TouchEnd to listeners that don't own an accepted touch

[Daniel d'Andrada]

When the owner of a touch accepts it, the other listeners must
receive a TouchEnd.

Even though there's code implementing the logic above in
ProcessTouchOwnershipEvent(), DeliverTouchEndEvent() was refusing to send
those TouchEnd events in this situatuation.
