[I] Group by rollup/cube/etc.. fails with new type_coercion [datafusion]
cetra3 opened a new issue, #25890:
URL: https://github.com/apache/datafusion/issues/25890
### Describe the bug
https://github.com/apache/datafusion/pull/23232 introduced some changes that broke some query shapes inadvertently.
### To Reproduce
Using datafusion cli:
```sql
CREATE TABLE t (ts TIMESTAMP, calls BIGINT) AS VALUES
('1970-01-01T00:00:00'::timestamp, 1),
('1970-01-01T00:01:00'::timestamp, 2),
('1970-01-01T00:05:00'::timestamp, 4);
SELECT date_bin('5 minutes', ts) AS bucket, SUM(calls)
FROM t GROUP BY ROLLUP(bucket) ORDER BY bucket NULLS FIRST;
```
You will get the error:
```
No field named "date_bin(Utf8(""5 minutes""),t.ts)". Did you mean '"ROLLUP (date_bin(Utf8(""5 minutes""),t.ts))"'
```
### Expected behavior
This query runs and returns appropriately
### Additional context
