    Pass on missing implementation while filtering

    The in_() filter isn't implemented yet for relations. Since these are
    being used in multiple locations in order to add new attributes to
    objects, we ignore the resulting error and allow the filtering to be
    applied by the corresponding result_filter hook afterwards.
