There are two ways of test service registration:
- manual call to `useAdditionalServices` in abstract test runner
- using of `additionalServices` property in one of test entity (e.g. in handler)
Services are registered in the same order (manual first, automatic second)
This led to the situation that if there was registered more specific
implementation of the service in the test configuration, it will be
overridden with regular implementation from handler, which is fixed
