Hannah Wolfe b2659d0cbb Refactor & test fixture migrations
refs #6301

Fixtures:
- Removed all the old (and now broken) 003 fixture upgrades
- Split the 004 fixture upgrade tasks out, each into their own file
- Improved the versioning code that figured out which upgrades we should do
- Added lots of test coverage to make sure all the fixtures are still being run correctly.

Permissions fixtures:
- Changed the code that was populating permissions fixtures to be more automated & based only on what is in the permissions.json file.
- Added lots of test coverage to make sure all the permissions are still being created correctly.

Merging the two things:
- Merged the content of permissions.json and fixtures.json into fixtures.json, but using the new structure from permissions.json.
- Changed to use the new automated model & relation creation for all fixtures, not just permissions.
- The only thing that can't be auto-populated just now is the owner creation, I think that's important enough to do separately.
- There were (so far) never any permission updates, so code for updating fixtures stays the same through the merge.
- This results in two clear code paths: populate (fill out a brand new DB) and update (make any changes since the last version)

Test coverage is now 100% across both updates and populations.
