test: account for pending deprecations in esm test

test-esm-local-deprecations fails if NODE_PENDING_DEPRECATION is set
because the test expects exactly the warnings it expects and no other
warnings. Modify the test to still expect its errors in the order it
expects them to, but to ignore errors it does not expect.
