If the specified query was added to the index, this method marks it as
not-computed and deletes the query results.

@param queryClass
@return query state iff the parameter was queried, added to the index,
and the query was computed just before the call and was marked
not-computed by this call, otherwise {@code null}.
If the specified query was added to the index this method marks it as not - computed and deletes the query results .
