    XDND: Fix dragMonitor leak in WorkspacesDisplay
    
    WorkspacesDisplay removes its dragMonitor in _dragEnd, but
    this was never called in when a xdnd drag ended causing
    dragMonitors to stack up and handling events multiple times.
    
    Fix that by making sure that _dragEnd is called when xdnd ends.
