 - for some reason we either (a) get duplicate events for user join from FS or (b) FS-ESL isn't handling
   the event properly. This results in duplicate entries on the user's list when user calls in from the
   phone. Check if a voice user with the same id is already in the voice conference and ignore the second
   event.

Client check - fixing a bug introduced by last commit

Client check - improvements to the webrtc related tests

improved the client check so now it uses sip.js and bbb_webrtc_bridge_sip.js from the bigbluebutton-client, so it's going to be easier to maintain; included some new callbacks on bigbluebutton-client related to the websockets; just after the webrtc test, the connection is closed

Minor change at the sip test

fixed the sip test changed since the last pull request, also adding more details when a rtmp connection is not successfully established
