[FEATURE] Support secure websocket connections. (#656)

Browse Source 
* Add WSS support for insecure scheme detection

WSS connections were broken by the introduction of this check. Adding WSS as a supported scheme for secure connections prevents a 401 being returned for an authorised connection.

* Add tests for WSS

Also extend HTTPS tests to ensure they do not catch WSS URLs
