Previously the tests tries to use UDP ports to fabricate ECONNREFUSED which is incorrect - UDP ports use different namespaces, so the port can have valid TCP listeners. This patch updates the test to fabricate the ECONNREFUSED error by using the port of a recently closed HTTP server. If the ephemeral port happens to be still open, try to get a different one until we succeed.
