Previously, we could in tests potentially run into listening port collisions resulting into `InvalidSocketAddress` errors. These errors could surface if we rolled port numbers that either collided with other concurrent tests *or* with other unrelated services running on localhost. Here, we simply let the OS assign us a free port number when setting up the testing nodes, which avoids such collisions altoghether (mod the potential TOCTOU race here, which we ignore for now).
