extending type doesn't support interface

[BleicherMagic]

Hi, I created an a extended class with GraphQLTypeExtension annotaion and added interface to it and when i checked the generated schema i didn't see that my type extended this interface example: `@GraphQLName("IcdAsset") public class IcdAsset extends IcdEntity {}

@GraphQLTypeExtension(IcdAsset.class) public class IcdAssetExtended implements EntityCommonInterfaceType { } @GraphQLTypeResolver(MockResolver.class) public interface EntityCommonInterfaceType {}

Generated schema: type IcdAsset { }(should be type IcdAsset extends EntityCommonInterfaceType) `
