[tracker-miners/wip/carlosg/tracker-3.0-api-breaks: 2/25] libtracker-miner: Create TrackerNotifier the new way



commit a2ee9d346dd65e774737ee5086dc44db97bc6117

    libtracker-miner: Create TrackerNotifier the new way
    
    It's no longer created from scratch, but retrieved from the
    connection. Also drop the NOTIFY_UNEXTRACTED flag since that is
    default.
