    downloader-view: change lifetime logic
    
    The DV follows the same goal as before (being alive while there are downloads).
    
    Now every download holds a reference to the DV and releases it when the
    download is removed (finished, cancelled, etc).
    The DV clears its own reference once and only once when a download is removed
    and there are no more downloads in queue.
    
    Bug #611779
