Previously, in the in-memory sorting module `LocalAggregationSorterListener` only the aggregate functions where used (grabbed by the `sortingColumns`). As a consequence, if the ORDER BY was also using columns of the GROUP BY clause, (especially in the case of higher priority - before the aggregate functions) wrong results were produced. E.g.: ``` SELECT gender, MAX(salary) AS max FROM test_emp GROUP BY gender ORDER BY gender, max ``` Add all columns of the ORDER BY to the `sortingColumns` so that the `LocalAggregationSorterListener` can use the correct comparators in the underlying PriorityQueue used to implement the in-memory sorting. Fixes: #50355 (cherry picked from commit be680af11c823292c2d115bff01658f7b75abd76)
