Plugin won't recognize @Named class

Nobody has claimed this yet.

I was trying to implement this pattern from documentation:

As for mapper itself, it is working fine and dandy. The plugin, however, seems to have problem with finding the annotated class which contains annotated mapping method. Error description is provided:

> "Unknown @ Named reference 'TranslationMapper' ".

Reference for "TranslationsToString" is found properly.

```
@Mapper(uses = TranslationMapper.class)
public interface PrimaryClassMapper {
@Mapping(source = "primary.id", target = "id")
@Mapping(
source = "primary.translatedNames",
target = "name",
qualifiedByName = {"TranslationMapper", "TranslationsToString"})
SecondaryClass toSecondaryClass(PrimaryClass primary, @Context Language targetLanguage);
}
```

```
@Named("TranslationMapper")
public class TranslationMapper {
@Named("TranslationsToString")
public String resolveTranslatedText(
List translations, @Context Language targetLanguage) {
//some fancy logic
}
}
```

Start by reproducing the warning with the PrimaryClassMapper and TranslationMapper examples in the issue, focusing on the class-level and method-level @Named annotations and the qualifiedByName reference. Done means the plugin recognizes the class-level "TranslationMapper" reference without reporting it as unknown while still resolving "TranslationsToString".
