pjsip: Clarify certificate configuration for Websocket.

Browse Source 
The Websocket transport uses the built-in HTTP server. As a result
the TLS configuration is done in http.conf and not in pjsip.conf.

This change adds a warning if this is configured in pjsip.conf and
also clarifies in the sample configuration file.
