Remove $nodeId from Token rule definition.

[SerafimArts]

The third argument to the Token rule is not needed and is not required at runtime or for some other things. We can get rid of it.

new Token($id, $name, $nodeId, $unificationId, $kept);
//                    ^^^^^^^ - excess

I read the code, and right now, I found no useful case where the $nodeId is used in the constructor. It is always set to null. I guess we can remove it!
