Fix long press after already moving off icon

When an icon is in the Hotseat and a user drags off from the icon,
but continues holding down, the icon gets a long press triggered
by the CheckLongPressHelper.

To fix this a check has been added on move events to see if the
point has moved outside the view and to cancel the long press
check callback if it has.
