8a224239c1 Prohibit optimize_aggregation_in_order with GROUPING SETS 
AggregatingStep ignores it anyway, and it leads to the following error
in getSortDescriptionFromGroupBy(), like in [1]:

    2022.05.24 04:29:29.279431 [ 3395 ] {26543564-8bc8-4a3a-b984-70a2adf0245d} <Fatal> : Logical error: 'Trying to get name of not a column: ExpressionList'.

v2: revert change to getSortDescriptionFromGroupBy() after
    GroupingSetsRewriterVisitor had been introduced
