refactor(tests): simplify test parameters and improve clarity

- Removed the `no_auto_upstream` parameter from the test function to streamline its signature.
- Updated the parameterized test case to focus on `skip_backfill` and `expected_changes`.
- Enhanced the test ID for better readability and understanding of the test's purpose.
