The AttachStateTransformer was never run in the destroy plan. This means that resource without configuration that used a non-default provider would not be connected to the correct provider for the plan. The test that was attempting to catch this only worked because the temporary graph used in the DestroyEdgeTransformer would add the state and detect some issues.
