[NodesConstraints] When swapping characters, node data is lost on bones added by plugins

[ManlyMarco]

When a character gets swapped out, the additional bones get deleted and then re-added. Anything that was referencing the old bones would need to get updated to reference the new bones I think node constraints is the right plugin to fix this in. The main issue appears to be node constraints getting lost when a character is replaced. It's not just bp bones, but any additional bone that is added to the character via modbone or bones framework
