    shell: Fix state of the "Party Mode" toggle item
    
    The "Party Mode" menu item is a toggle menu item. If we only listen to
    the "activate" signal, we'll listen for clicks, but we won't change the
    state. So when the gear menu appears, the old state would be shown.
    
    Listen to the state change instead, and update the action state.
