Maintenance tasks before release

[stuartcampbell]

This is a collection of some cleanup tasks that I kept meaning to do.

1. Removed storing keys in database for testing
2. Added api_key and admin_api_key fixture so tests can access an api key to use in testing
3. Code formatting applied
4. Fixed some code linting errors
