… plan
## What changes were proposed in this pull request?
Changed `TreeNode.argString` to handle `CatalogTable` separately (otherwise it would call the default `toString` on the `CatalogTable`)
## How was this patch tested?
- Expanded scope of existing unit test to ensure that verbose information is not present
- Manual testing
Before
