LastValueAggFunctionWithOrderTest compilation error due to incompatible
types

I would decrease the priority of this issue. It's a problem of the test itself. Imo the problem is that the type hierarchy of the test infrastructure is overcomplicated and there is little control over type bounds in that test. Moreover it appears only occassionally.
Nevertheless I would aim to simplify these tests.
