Too lax unique constraints for Thumbnail coped with "on demand" thumbnail generation may leave database in inconsistent state where two thumbnail for the same size are saved. We should be able to prevent that from happening by generating all thumbnails when we save the image. Should fix #24, but I can't figure out a way to actually test it.
