(BUG) document_retagger wont work for tags

[HungyBird]

Hi,

I receive an error when trying to retag via commandline.
Using the same command with "-c"-option works!

~/paperless-ng $ docker-compose exec webserver document_retagger -T

Found the error: had a tag which contains "word" in the assignment of a tag. this seems to break the script. dont even know if it is necessary to include "*" in the tags

[jonaswinkler]

Including "*" is most likely what's causing the issue here, and no, that's not required. Simply put a couple words in the match field that need to appear in the document.
