    miner-fs: Only process nfo:FileDataObject resources
    
    The motivation for this commit is that the 600-applications-camera.py
    functional-test would trigger the following warning:
    
       (tracker-miner-fs:28346): Tracker-CRITICAL **: tracker_string_to_date: assertion 'date_string' failed
    
    The cause was in tracker-file-notifier.c:sparql_files_query_cb(), which
    processes a query that expects every resource with an nie:url property
    to also have nfo:fileLastModified property.
    
    Not all resources correspond to files. I think the TrackerMinerFS should
    only be processing resources that have type nfo:FileDataObject, not all
    resources with URL
