The features stanza sent to the client says that client can either
start TLS or login using X-GOOGLE-TOKEN. Because X-GOOGLE-TOKEN is
not documented and subject to change, your only choice is to start TLS
by sending <starttls/> to the server.
After the stream is started on TLS, the server will send the client a
features stanza containing SASL PLAIN.
I recommend using SASL authentication (XMPP Core, section 6) instead
of Non-SASL Authentication (JEP-078).
I'll update the error messages to make them more clear.
