run AttachStateTransformer in destroy plan

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.
