discovery: test coverage for issue4438 / 86c35b7ae300 / 73cfaa348650

The randomness in the discovery protocol made this problem hard to reproduce.
The test mocks random.sample to make sure we hit the problem every time. The
set iteration order also made the output unstable ... but with the issue fixed,
it is stable.
