HTML5: Fix issue with listenOnly not hanging up

 Add catch all exception to bbb-web redis subscriber

Improve document conversion and make it faster

 On redis-cli, we noticed that BbbWebSub isn't on the "client list". The auto-reconnect on bbb-web
 wasn't triggered as not log was generated in bbb-web.log. Maybe the exception was something we
 did not handle. Try catching all exception on this jedis connection.
