The test already attempts to connect to a server on the loopback address with setup that leads to the "no suitable proxy" scenario. I suspect the proposed patch is okay but I'd prefer to wait until @dfuch is back (Daniel has been doing a lot of work on test stability in this area and will probably want to run the change on a wide range of OS/configurations to check that it is stable).
