> Ascending rule match with RelSubset operand doesn't work

>
> Given a rule with match pattern {{operand(Filter, operand(RelSubset))}}, when
> we add a new RelSubset into the set, planner will fire rules for RelSubset.
> But in {{VolcanoRuleCall.matchRecurse}}, if !inputRels.contains(previous), it
> will skip. Obviously, the input rels will never contain a RelSubset, hence
> fails to match the rule.
