remove /b/ between server and room-id-from-greenlight

[jeau]

Thank you for your work

to access my server I don't have /b/ between my bbb server address and the room id from greenlight.
bbb-streaming can't connect because it rebuilds the url with this /b/ (it's glin my case, see example below)

The error message:

During handling of the above exception, another exception occurred:

Please patch this for yourself for now. I'll add a lot more options about how to enter rooms etc. in the near future, for now that's just test code to get it to somehow join a server.
