fix(breakout,av-moderation): support non-ascii room names
fix(breakout,av-moderation): support non-ascii room names

rooms are created in prosody in their urlencoded form, eg täst
becomes t%c3%a4st@conference.jitsi.example.org

As local params = formdecode(query) contains an urldecode, we
need to reencode the room name so that the room can be found in
prosody.
