Pull request description:

  Should fix https://github.com/bitcoin/bitcoin/issues/26364

  I can't reproduce this, but my guess would be that `PeerNoVerack::on_version`, which sends the `wtxidrelay` message, is executed in the event loop and thus may run after the main thread sending `msg_verack`.

  Also, fix another bug.

  Finally, add some `assert_debug_log` to ensure the right code branch is executed (and not some random, unrelated disconnect).
