### Describe the bug

When I try to update the credentials for my Apple OAuth Provider, the changes are not detected when checking resource status or attempting to push.

Another strange thing I observed is that after creation of the auth resource with my apple oauth provider configured, the Hosted UI doesn't render.

Links and Scripts in the Header contain `null` in parts of the CDN urls

Hosted UI Endpoint : https://remixamplified169d1d34-169d1d34-dev.auth.us-east-1.amazoncognito.com/

Test Your Hosted UI Endpoint : https://remixamplified169d1d34-169d1d34-dev.auth.us-east-1.amazoncognito.com/login?response_type=code&client_id=j72tq46t3ecn7ru5hh2osi9gm&redirect_uri=http://localhost:3000/

### Expected behavior

Changes to `hostedUIProviderCreds` should be detected on `amplify push` and/or `amplify status`

Hosted UI Endpoint should load styles and scripts and render the login form properly

### Reproduction steps

1. `amplify init`
2. `amplify add auth`
3.
