Purpose

This PR is to fix the: https://jira.autodesk.com/browse/DYN-4460.

When a new custom node is created and saved to a local path in a dynamo session, the custom node manager doesn't have the path information for that particular custom node. It will only have the path information after dynamo is restarted because Dynamo tries to load all the definitions from the node package paths. This was happening because when the CN is saved, during the InternalSaveAs method in dynamo view model, the workspace model's save function is always called.

This save method on the CustomNodeWorkspaceModel model is never called: https://github.com/DynamoDS/Dynamo/blob/master/src/DynamoCore/Graph/Workspaces/CustomNodeWorkspaceModel.cs#L298. When the custom node workspace is being saved, this method has to be called and that will make sure that the path information is updated in the custom node manager.
