[CALCITE-5742] SubstitutionVisitor Causes Infinite Loop when using AggregateOnCalcToAggregateUnifyRule
The input of Calc Under Aggregate was changed when executing permute in AggregateOnCalcToAggregateUnifyRule, then If this match can't produce result, Visitor can not skip out because the condition "queryDescendant == r.after" is not met. I changed it to use clone of input, when original input would not be changed when this result is null.
