[tracker/wip/passive-extraction: 8/16] tracker-extract: Do not add statistics data if no module handled the file

[Martyn James Russell <mr src gnome org>]

commit eb7ca23c35a2f3094c4e09a26933626581ee7bdf
Author: Carlos Garnacho <carlosg gnome org>

    tracker-extract: Do not add statistics data if no module handled the file
    
    This prevents a crash when reporting the statistics later, as there is a
    NULL key that is expected to be a GModule.
