OS/device including version:

Windows 10 GTX 1060 6GB

Issue description:

If you have a Remote node with Named Parameters, as well as Linked Controls and/or Configurations, and you delete all nodes that a Linked Control or Configuration is linked to, all Named Parameters will be removed from the Remote node in addition to the Linked Control or Configuration.

Steps to reproduce:

1. Add a few nodes
2. Add a Remote Node
3. Add a few Named Parameters to the Remote Node
4. Add some Linked Controls or Configurations to the Remote Node
5. Delete all nodes that are linked to from one of the Linked Controls or Configurations
6. That Linked Control or Configuration will be removed from the Remote node as expected, but also all Named Parameters will be removed. Linked Controls or Configurations that still have nodes linked to them should still be there.
