Merge bitcoin/bitcoin#30445: test: addrman: tried 3 times and never a success so isTerrible=true

1807df3 test: addrman: tried 3 times and never a success so `isTerrible=true` (brunoerg)

Pull request description:

  This PR adds test coverage for the following verification:
  ```cpp
  if (TicksSinceEpoch<std::chrono::seconds>(m_last_success) == 0 && nAttempts >= ADDRMAN_RETRIES) { // tried N times and never a success
      return true;
  }
  ```

  If we've tried an address for 3 or more times and were unsuccessful, this address should be pointed out as "terrible".
