Don't update listener after deactivating implicit pointer grab

Browse source 
After the pointer grab is deactivated, the touch listener record is
updated at the end of DeliverTouchEmulatedEvent. However, the touch
record is ended when the grab is deactivated, so the update to the
listener record is in an array of memory that has been freed.
