    ontology: Remove tracker:writeback property from nao:prefLabel
    
    Fixes NB#278806, this property only applies to nao:Tag entities, not
    on files, so whenever a file with XMP keywords was added, the insertion
    of the keywords would trigger a writeback petition in the miner. This
    would add a writeback task that would issue a costly query only to find
    out it doesn't directly affect any nfo:FileDataObject.
    
    If several files with these characteristics were created, the effect
    would be multiplied as writeback petitions would be requested faster
    than delivered, filling the writeback queue and hence blocking any
    other processing.
