Amend anomaly subscriber acceptance test to accommodate TypeSet

- Checking the exact values of a nested Set or List value is not
  recommended or necessary:
  - Faulty errors can result from changed indices
  - Testing framework will already return failure if there is a mismatch
    with specified config during ImportStateVerify
- If check *is* necessary: should use TestCheckTypeSetElemNestedAttrs
