    libgdm: Unref the manager propagated from task
    
    This instance has already been reffed when passed to the task, and since
    we're stealing it with `g_task_propagate_pointer` it won't be unreffed.
    
    We could also do this in the `on_reauthentication_channel_opened` callback
    but since the new task will ref it anyway, we can just be clean and do it
    here.
