These were not testing the same thing as the comparable Assert in calc_nestloop_required_outer(), because we neglected to map the given Paths' relids to top-level relids. When considering a partition child join the latter is the correct thing to do. This oversight is old, but since it's only an overly-weak Assert check there doesn't seem to be much value in back-patching.
