fix(registry): enhance provider config validation and update error handling in tests

- Added a check for null or undefined config in registerProviderConfig function.
- Updated tests to ensure proper error messages are thrown when no providers are registered.
- Adjusted mock implementations in generateImage tests to reflect changes in provider model identifiers.
