SMACK-395 Socks5BytestreamManager.establishConnection(): Don't bail out with an Exception uf the local XMPP service does not support Service Discovery (e.g. talk.google.com). Instead remember the Exception and give the local proxy (if enabled) a chance.

Also compute the digest only if it's really needed, that is when streamHosts is not empty.
