I think the root cause is that the Aggregate operator is treated as
resolved if even it has group by ordinals.
For example:
```
'Filter ('a > 0)
+- Aggregate [2], [count(1) AS count(1)#83L, a#81]
+- SubqueryAlias tmp
+- Project [1 AS a#81]
+- OneRowRelation$
```
Aggregate is treated as resolved even if it has a group by ordinal "2".
Then, it tries to resolve the `Filter` by putting the `Filter` as a
aggregation expression:
```
!'Aggregate [2], [('a > 0) AS havingCondition#84]
+- SubqueryAlias tmp
+- Project [1 AS a#81]
+- OneRowRelation$
```
Actually this plan is already wrong. As we are asking for ordinal "2", but
actually there is only one
aggregation expression `[('a > 0) AS havingCondition#84] `
