I realized quite late, that it was also required to lookup the
"nsruvReplicaLastModified" attribute from the in-memory RUV.
This third review is to also report this attribute (in addition to
"nsds50ruv") and to fix a problem in search_requested_attr where only
the first attribute of the request was evaluated.
Sorry for the "invalid" previous review :-[
