[tracker-miners/wip/carlosg/tracker-3.0-api-breaks: 9/40] libtracker-miner: Create TrackerNotifier the new way

[Carlos Garnacho <carlosg src gnome org>]

commit 4f1a3d590f6b64e09ce2de170a7a427a61159d93

    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.
