[ShaderGraph] No exception thrown when connection to the node is unsuccessful

Package: Shader Graph

-

How to reproduce:
1. Open VM > Bug Attachments > project > '1177682-Shader-Graph-Exception-Issue'
2. Open Assets > ScopeErrors_Start.shadergraph
3. Select 'Add' node and 'Sample Texture 2D' node
4. Right-click > Convert To Sub-Graph > Save
5. Disconnect Position(3) port from 'PBR Master' node
6. Connect Position(3) port to 'PBR Master' node
- Notice that nodes aren't connected

Expected result: Exception is thrown
Actual result: Exception is not thrown

Reproducible with: 2019.2.2f1 (Shader Graph 5.2.3), 2019.3.0a12 (Shader Graph 7.0.1), 2020.1.0a1 (ShaderGraph 7.0.1)
Could not test: 2017.4 because ShaderGraph is not compatible, 2018.4 due to errors, 2019.3.0a1 Shader Graph freeze

Note: After the nodes conversion to a SubGraph edge remains connected when the edge is disconnected manually, reconnecting is unavailable.

  1. Resolution Note:

    There currently isn't a good solution to this issue. Once we have a clearer separation between vert and frag stages, we will have the tools available to solve this.
