Auto-registration of @GraphQlRepository doesn't work if the returned list is declared not null

[andreysubbotin]

Example query:

"Query root"
type Query {
  petList: [Pet]!
}

Data Repository:

@GraphQlRepository
public interface PetRepository extends JpaRepository<Pet, Long>, QuerydslPredicateExecutor<QPet> {
}

AR: Spring GraphQL unable to handle petList query.
Perhaps, GraphQL type is not resolved correctly in org.springframework.graphql.data.query.AutoRegistrationRuntimeWiringConfigurer.AutoRegistrationWiringFactory#getOutputTypeName.

The Java type name QPet doesn't match the GraphQL type name Pet, so auto-registration won't match them for use with Querydsl. However, it should match the Pet from JpaRepository for use with Query By Example.

I think there is indeed an issue with a not null list specifically, which should be fixed in 1.2 snapshots as a result of a recent change. However, it needs to be backported to 1.1. Can you confirm it does work if the list is nullable?
