    clutter/click-action: Do not process captured event if action is disabled
    
    Disabling a click action after a button-press but before a
    button-release is captured makes ClutterClickAction connect to
    captured-event and never disconnect.
    
    This change fixes it by making sure the captured-event is only
    processed if the action is still enabled, otherwise releasing
    the action (reset state) and propagating the event.
