// Issue https://github.com/hashicorp/nomad/issues/2583 uncovered

// allocation from the scheduler has its job normalized and the FSM
// will only denormalize if the allocation is not terminal. However
// if the allocation is garbage collected, that will result in a
// allocation being upserted for the first time without a job
// attached. By returning an error here, it will cause the FSM to
// error, causing the plan_apply to error and thus causing the
// evaluation to be failed. This will force an index refresh that
