Those two fixtures only exist as annotation versions. Their attribute counterparts were missing.

The corresponding tests only expected a `LogicException` which is what `AnnotationClassLoader` would raise for undefined classes as well.

This PR adds new assertions for the exception messages which would have discovered the missing fixtures. Finally, the two missing fixtures are added.
