    wayland: Fix some dnd corner case
    
    We must call gdk_drag_drop_done() when the drag ends,
    successfully or not. Without this, we get an unwarranted
    emission of ::cancel after a successful drop.
    
    Since only the first call to gdk_drag_drop_done() is taking
    effect, it is safe to call as a fallback, after emitting
    ::dnd-finished. If the application connects to that signal
    and calls gdk_drag_drop_done() itself, its call will take
    precedence.
    
    This matches what the X11 implementation does.
