tests: Fix call assertion

Under py312, MagicMock.has_calls raises an AttributeError. This is
actually a good thing, as previously we weren't actually making the
assertions we thought we were making.

Fix the one place that we forgot the leading `assert_`, and switch it
to `any_order=True`; this is required for the test to pass, as there
are additional calls between the two expected calls.

See python/cpython@1d4d677d
