Affects Version/s: 7.0.0 M3

Data migration from DBStore does not delete thumbnails or previews when "delete files from previous repository" is checked.
1. Upload an image file in the document library
2. Go to Server Administration > Data Migration
3. Check "delete files from previous repository" and migrate to DBStore
All files would be removed from the bundles/data/document_library folder.
Thumbnails are left behind.
