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 :-[
