title: Entity Graph ignored when loading related entities
body: <p>I have an entity graph defined in my Person entity. When I declare the phone attribute as an attribute node, a join clause is created and only one select is executed, as expected. But when I remove the phone attribute from the entity graph, the phone field is still loaded, but now with a new select query for each Person retrivied. Is it possible to ignore an attribute in a particular EntityGraph?</p>
  
  <p>Person Entity:</p>
  
  <pre><code>@Entity
  @Table(name = "person")
  @NamedEntityGraph(
      name = Person.PERSON_LAZY,
      attributeNodes = {}
  )
  public class Person {
  
      public static final String Person_LAZY = "person.lazy";
  
      @Id
      @Column(name = "id")
      private Long id;
  
      @Column(name = "name")
      private String name;
  
      @JoinColumn(name = "phone")
      @ManyToOne
      private Phone phone;
  }
  </code></pre>
  
  <p>PersonRepository:</p>
  
  <pre><code>@Repository
  public interface PersonRepository extends JpaRepository&lt;Person, Long&gt; {
  
      @EntityGraph(value = Person.PERSON_LAZY, type = EntityGraphType.FETCH)
      @Query("SELECT p FROM Person p")
      public List&lt;Person&gt; findAllLazy();  
  }
  </code></pre>
