Fixes crashing jwt util for anonymous domains.

Room name verification crashes when we have a configured anonymousdomain as it doesn't have any token extracted data. It is safe to skip this check as room creation is verified by jicofo and we have the option restrict_room_creation to admin users.
Removes obsolete print when updating jitsi-meet-tokens.
