[brasero/wip/carlosg/tracker3: 23/24] Observe nfo:FileDataObject/nie:InformationElement split

[David King <davidk src gnome org>]

commit b41d69ac256c6098e6e9bae70491d9d1687b0ce6
Author: Carlos Garnacho <carlosg gnome org>

    Observe nfo:FileDataObject/nie:InformationElement split
    
    These resources are interpreted differently in Tracker 3.0 compared
    to older versions, the newer version makes those 2 different resources
    (one representing the "file", other the "content) that relate to each
    other. In older tracker versions, these 2 aspects were conflated in
    a single resource.
    
    The query is implicitly crossing that barrier, so make it explicit.
    With this change, the query may run with either version.
