The method `ResolveAggregateFunctions.resolveFilterCondInAggregate` aims to
do the two things
1. resolve the expression in having.
2. push the having extra agg expression to `Aggregate`
However we only care about 2. If having clause resolution is successful but
not exists extra agg expression, we will ignore the resolution. Here is a
example:
```
-- Works resolved by `ResolveReferences`
select c1 from values (1) as t1(c1) group by grouping sets(t1.c1) having c1
= 1
-- Works because of the extra expression c1
select c1 as c2 from values (1) as t1(c1) group by grouping sets(t1.c1)
having t1.c1 = 1
-- Failed
select c1 from values (1) as t1(c1) group by grouping sets(t1.c1) having
t1.c1 = 1
```
It wroks with `Aggregate` without grouping sets through `ResolveReferences`,
but Grouping sets not works since the exprId has been changed.
