    appIcon: End running drag operations on destroy
    
    AppIcon makes itself draggable, and handles the various DnD
    routines such as 'drag-begin' and 'drag-end' by making the
    Overview emit the appropriate signals.
    
    However, when destroyed, the AppIcon does not try to finish
    any drag operations that started. That causes the event
    blocker in AllView not to be updated correctly when dragging
    icons to outside folders.
    
    Make AppIcon emit 'item-drag-end' when a drag operation
    started and it's destroyed.
