Fix not in aggregate's output err after eliminate by uniform when group
sets exist

if query as following, would cause `ERROR 1105 (HY000): errCode = 2,
detailMessage = GROUPING_PREFIX_event_name_group not in aggregate's
output`

the pr fix this

```sql
SELECT
  CASE WHEN GROUPING(event_date) = 1 THEN '(TOTAL)' ELSE CAST(event_date AS VARCHAR) END AS event_date,
  user_id,
  MAX(conversion_level) AS conversion_level,
  CASE WHEN GROUPING(event_name_group) = 1 THEN '(TOTAL)' ELSE event_name_group END AS event_name_group
FROM
  (
    SELECT
      src.event_date,
      src.user_id,
      WINDOW_FUNNEL(
        3600 * 24 * 1,
        'default',
        src.event_time,
        src.event_name = 'shop_buy',
        src.event_name = 'shop_buy'
      ) AS conversion_level,
      src.event_name_group
    FROM
      (
        SELECT
          CAST(etb.`@dt` AS DATE) AS event_date,
          etb.`@event_name` AS event_name,
          etb.`@event_time` AS event_time,
          etb.`@event_name` AS event_name_group,
          etb.`@user_id` AS user_id
        FROM
          `test_event` AS etb
        WHERE
          etb.`@dt` between '2025-09-03 02:00:00' AND '2025-09-10 01:59:59'
          AND etb.`@event_name` = 'shop_buy'
          AND etb.`@user_id` IS NOT NULL
          AND etb.`@user_id` > '0'
      ) AS src
    GROUP BY
      src.event_date,
      src.user_id,
      src.event_name_group
  ) AS fwt
GROUP BY
  GROUPING SETS (
    (user_id),
