[tracker/tracker-0.12: 132/202] tracker-extract-gstreamer: Don't pass file URL needlessly

    tracker-extract-gstreamer: Don't pass file URL needlessly
    
    Also some changes to avoid confusion:
    
    * Rename 'uri' to 'file_url' when there are lots of URIs around
    
    * Rename add_date_time_gst_tag() (which still uses the file URL
      to guarantee metadata) to add_date_time_gst_tag_with_mtime_fallback()
