Fix bug with missing policiy revision

[steverydz]

Done

Fixed a bug where the "Policy revision" column wasn't populated on the models page

How to QA

• Go to https://snapcraft-io-4347.demos.haus/login-beta and login
• Go to https://snapcraft-io-4347.demos.haus/admin/njwQYXFnS7ppo7LaGxoh7aqVZc1CPi26/models
• Check that the "Policy revision" column is populated for the "test_model_without_api_key" model (it might take a moment due to doing multiple requests)
