Ticket 47323 - resurrected entry is not correctly indexed
    
    Bug Description:  If a tombstone entry is resurrected to a glue entry
                      the indexes are not updated correctly.  The objectclass
                      index still shows the resurrected ID in the nsTombstone key.
    
    Fix Description:  Add the correct EQUALITY flag to the index delete function.
                      Otherwise the delete operation is skipped in
                      index_addordel_values_ext_sv().
