In the previous CL I said that this worked fine with all '?' but failed with '&'
- that is indeed true. With '?' the arguments weren't actually acknowledged so
the fallback (online apprtc server) was used. But with '&' the incorrect
argument "http://localhost:8089" was sent, causing an error internally because
after some passing around the URL became "ws://http://localhost:8089".

+          "debug=loopback&ts=&wshpp=localhost:8089&wstls=false");
