    libtracker-data: Improve changes over single valued ontology properties
    
    Things like rdfs:label and rdfs:comment that are not tracker through the
    TrackerOntology and are single-valued may result in errors if there's
    changes on those.
    
    Handle those better by replacing the value instead of trying to insert
    over it.
