subclasspropagation(): Squash two more bogus hash(x) == id(x)

tests.  Alas, because only the "x86 OpenBSD trunk" buildbot fails
these tests, and test_descr stops after the first failure, there's
no sane way for me to fix these short of fixing one and then
waiting for the buildbot to reveal the next one.
