Failed ugoira conversions counted as successful downloads

[WhiteSp1rit]

Description

If a conversion from ugoira to webm, webp or something else fails, this does produce an error, however the download still counts as successful and is written into the database. Ugoira then get deleted (if said entry is enabled in config.ini), you get no files, but you can't re-download either as attempting to do so will check that the file was successfully download in DB.

Steps to Reproduce

1. remove path to FFMpeg fro config.ini
2. download any ugoira image
3. try to re-download it - download is rejected, as the file is counted as successfully downloaded in DB

"You can get this information from executing PixivUtil2.py --help." - you actually can't, it doesn't list how to find out the version.

Due to this, now I have possibly hundreds of ugoira images missing, but marked as downloaded - how can I fix this?
Re-downloading doesn't work as I mentioned. Removing database check will re-download everything, including the files which were already moved/deleted. Any way to re-downlaod just the missing Ugoira images, ignoring their falsely written DB entries?
