streamReplyWithRange: Redundant XSETIDs to replica
streamReplyWithRange: Redundant XSETIDs to replica

propagate_last_id is declared outside of the loop but used
only from within the loop. Once it's '1' it will never go
back to '0' and will replicate XSETID even for IDs that
don't actually change the last_id.
While not a serious bug (XSETID always used group->last_id
so there's no risk), it does causes redundant traffic
between master and its replicas
