Fix broken ocrd_network processing worker logs

[MehmedGIT]

The processing worker logger acted weirdly for some time. Pay attention to the log levels produced by self.log.__dict__

To reproduce it is enough to print the logger object at the beginning of each method:

self.log.warning(f"{self.log.__dict__}")

Seems when jiggling with the logging in the past, the initLogging() call was removed from the processing worker. The logger level is still set to INFO at some point, but an implicit call to initLogging() sets the logger level earlier. I think we had to remove that call in the past because initLogging() was called in other places which led to conflicts.
