Always subscribe to log updates
Always subscribe to log updates

When the job is restart, we will not get any updates unless we're
subscribed to job updates - that's why we need to subscribe even if the
job is already finished.

The other option to fix this would be to subscribe and unsubscribe also
based on the status, but since subscribing to finished jobs does not
cost us anything, I prefer the simpler solution.
