- Fix a bug, which caused the get-full-texts request to fail, because of the wrong "requestAssignmentsCounter".

- Fix a bug, which caused multiple workers to get assigned the same batch-counter, while the assignment-tasks where different.
- Set a max-size limit to the amount of space the logs can use. Over that size, the older logs will be deleted.
- Show the error-message returned from the Worker, when a getFullTexts-request fails.
- Improve some log-messages.
- Update dependencies.
- Code cleanup.
