Don't call simplify_aggref with a NULL PlannerInfo 42473b3b3 added prosupport infrastructure to allow simplification of Aggrefs during constant-folding. In some cases the context->root that's given to eval_const_expressions_mutator() can be NULL. 42473b3b3 failed to take that into account, which could result in a crash.
To fix, add a check and only call simplify_aggref() when the PlannerInfo is set.
