fix finish flag in subscription engine

[DavidBadura]

The flag is there to identify whether work still exists. "No subscriptions" was incorrectly marked as not finished because the flag was just named "streamFinished". I renamed the flag and included this case as "finished".

Otherwise you would have an endless loop in the boot because there was nothing to boot, but it wasn't set to finished either.
