komga: Infinite "FixThumbnailsWithoutMetadata" scan with "Fixed 0 ThumbnailBook"

Steps to reproduce

Komga directly run the task “FixThumbnailsWithoutMetadata” and the problem start. The problem seems to occur when upgrading the docker image from 1.8.3 to 1.8.4 (latest). Rollback 1.8.4 to 1.8.3 and 1.7.2 without improvement.

Expected behavior

Komga start and task “FixThumbnailsWithoutMetadata” completed successfully.

Actual behavior

The scan “FixThumbnailsWithoutMetadata” never end and fix no “ThumbnailBook” (=> produce high CPU usage).
