LogicEditor | Copy-pasting nodes throws nullRef for edges

Summary

When copying and pasting a node setup with edges, all edges will get lost, throwing a nullRef for each edge.

Steps to reproduce

1. Build a node setup, e.g. [I] Object Info connected to [R] Visibility
2. Copy the setup
3. Paste the nodes
4. Edges will not be copied and nullRef will be thrown

What is the current bug behavior?

Edges in node setups can not be copied and pasted

What is the expected correct behavior?

Edges should persist pasting
