Node execution order not updated when authoring graph node positions are changed

Steps to reproduce:
1. Create a new Behavior Graph asset
2. Add multiple sequential nodes (e.g., Action nodes) connected in a sequence
3. Initially arrange nodes from left-to-right in the desired execution order
4. Inspect the runtime graph inspector and take note of the actions order
5. Move one or more nodes to change their left-to-right visual order in the authoring graph
6. Inspect the runtime graph inspector again

Actual results: 

• The actions order of execution is not changed

Expected results: 

• The actions order of execution of the runtime graph reflect the authoring graph

Reproducible with versions: 1.0.0, 1.0.12
