Testing: fix @MockitoConfig(convertScopes=true) with auto-producers

The annotation transformer in `SingletonToApplicationScopedTestBuildChainCustomizerProducer`
has to:

- look for the `@Produces` annotation in ArC's `AnnotationStore`, not in Jandex;
- run _after_ the annotation transformer in `AutoProducerMethodsProcessor`.

This is enough to recognize an auto-producer (producer without `@Produces`).
