    libtracker-data: Do not error on NULL arguments in tracker:uri-is-parent
    
    This may happen during query evaluation, without the query explicitly
    specifying any NULL value. If we error out, query execution will
    definitely stop, and the error may propagate further up.
    
    Just tiptoe over those values, and let query evaluation continue
    further, the right results will be eventually returned.
