Jigasi Transcription Problem - Reading from SSRC while it is not known as a participant

@shooding “room is null” issue can be resolved by commenting bosh url. Unable to invite transcriber due to no Jigasi instances being available - #39 by Prashanth

Thanks to @damencho @Prashanth
my transcriber starts working after purge jigasi and reinstall again.
Then follow @Prashanth suggestion to comment out
