Fix handling of Bolt init auth metadata

Browse Source 
Summary:
Our implementation of the Bolt protocol now correctly handles INIT message
metadata used for authentification. The related description from the Bolt
standard is: 'The token must contain either just the entry {"scheme": "none"}
or the keys scheme, principal, and credentials. Example {"scheme": "basic",
"principal": "user", "credentials": "secret"}". If no scheme is provided, it
defaults to "none".'
