Following sequence of queries produces `UNSUPPORTED_GROUPING_EXPRESSION`
error:
```
create table t1(a int, b int) using parquet;
select grouping(a), dummy from t1 group by a with rollup;
```
However, the appropriate error should point the user to the invalid `dummy`
column name.
Fix the problem by deprioritizing `Grouping` and `GroupingID` nodes in plan
which were not resolved and thus cause the unwanted error.
