Use actual graphql name on extending type

[geichelberger]

If a type is extended via a GraphQLTypeExtension annotation, the simple class name is used instead of checking whether a GraphQLName annotation is available; if the GraphQL name differs from the class name, the field cannot be fetched.

Example:

All the fields from the GqlCurrentUser class will be added with CurrentUser as the parent name. While handling the extension, the fields will be registered with GqlCurrentUser as the parent name, which does not match the actual parent.

@GraphQLName(GqlCurrentUser.TYPE_NAME)
public class GqlCurrentUser {

  public static final String TYPE_NAME = "CurrentUser";

}

@GraphQLTypeExtension(GqlCurrentUser.class)
public class EventCurrentUserExtension {
}

graphql-java-annotations/src/main/java/graphql/annotations/processor/typeBuilders/OutputObjectBuilder.java

Line 82 in 74dd8c8

GraphQLFieldDefinition gqlField = graphQLFieldRetriever.getField(typeName, method, container);

vs

graphql-java-annotations/src/main/java/graphql/annotations/processor/retrievers/GraphQLExtensionsHandler.java

Line 62 in 74dd8c8

addExtensionField(fieldRetriever.getField(object.getSimpleName(), field, container), fields, definedFields);

I added a test case that fails without the patch

Hi Geichelberger,

Thanks for your contribution! Great job on the GraphQL extensions name resolution. Merging now.

Best,
Kevan.
