Resolve broken fixtures in dev dataset script for local Dandi

[aaronkanzer]

Validation for creation of Django objects was failing prior to changes when running:

docker-compose run --rm django ./manage.py create_dev_dandiset --owner your.email@email.com

This PR resolves errors within this script to ensure correct setup locally

Hi @aaronkanzer , thank you for the patch! As I see that there is a dedicated http://github.com/dandi/dandi-archive/blob/HEAD/dandiapi/api/tests/test_create_dev_dandiset.py and I see it passing recently

could you

• elaborate on the failure (is it a new fail or something "introduced" recently?)
• see if you can adjust/extend that test so it demonstrates prior issue which this PR fixes?

I second @yarikoptic's requests -- without knowing the exact failure you encountered, it's hard to review this and understand the added value. Thanks @aaronkanzer!

Closing due to duplicative code in #1809

@yarikoptic @waxlamp if you wouldn't mind taking a look there, that would be great!

The exact failure that should answer #1722 (comment) is included in the description of the PR. Thanks!
