pg_plan_advice: Avoid assertion failure with partitionwise aggregate.

An Append node that is part of a partitionwise aggregate has no
apprelids. If such a node was elided, the previous coding would
attempt to call unique_nonjoin_rtekind() on a NULL pointer, which
leads to an assertion failure. Insert a NULL check to prevent that.
