    tracker-miner-fs: Make graph-specific data optional on deletes
    
    Depending on the file type and its processing state, we may expect
    nfo:FileDataObject and/or nie:InformationElement data in the content-
    specific graphs.
    
    The delete operations should account for those not being yet added,
    or simply missing due to the file type. This fixes delete operations
    after the nfo:FileDataObject/nie:InformationElement split.
