handle retracted tx status properly

[brenzi]

Since > 0.12.12 we ignore the tx status retracted. before it was interpreted as failed.

The question is: what edge cases can occur that would lead to failures in the worker

Maybe if the extrinsic depends on state which is orphaned as well but the worker isn't aware? But then the problem is bigger anyway. (that's why we wait for finalized for any enclave invocations)

If we are sure we're ok, close this without action
