…a value
The factory function for the `reporter:angular--polyfills` Karma plugin did not return a value, which violates Karma's plugin contract. This could cause Karma to crash when multiple reporters were in use, particularly with tools that use Karma's multi-reporter functionality.
This change modifies the factory to return an object with an empty `adapters` array (`{ adapters: [] }`). This satisfies Karma's plugin requirements and ensures compatibility with the multi-reporter, preventing the crash.
