The test expectations change because there are some test messages.in files that contained unannotated messages with replies, such as TestWithLegacyReceiver.CreatePlugin, which were assumed to be synchronous and now are assumed to be async. I programmatically verified that no non-test message receivers were like this, and I verified that the output is binary equal before and after this change.
