Removes disableRoomNameConstraints option.

This option is useless, as if we do not need to verify room name, we just disable the mod_token_verification module.

     if self.allowEmptyToken == true then
         module:log("warn", "WARNING - empty tokens allowed");
     end
 
     local roomClaim = claims["room"];
-    if roomClaim == nil and self.disableRoomNameConstraints ~= true then

         return nil, "'room' claim is missing";
     end
