Once again we're caught out by sharing the same output value node type between the plan phase and the apply phase. To allow for some slight variation between plan and apply without drastic refactoring here we just add a new flag to nodeExpandOutput which is true only during the planning phase. This then allows us to register the checkable objects only during the planning phase and not incorrectly re-register them during the apply phase. It's incorrect to re-register during apply because we carry over the planned checkable objects from the plan phase into the apply phase so we can guarantee that the final state will have all of the same checkable objects that the plan did. This avoids a panic during the apply phase from the incorrect duplicate registration.
