hash notification log message is misleading
The following message is misleading.  After its printed 118 notification were queued for processing, they may not be finished.  The word `processed` seems to imply they were finished.

```
19:45:18.389 [HashNotificationFinder ScanTask] DEBUG i.f.core.worker.finder.hash.ScanTask - Scanned 50 of 68 tablets, processed 118 notifications, sleeping 0
