Hooks are not applied on objects build from InterfaceBuilder and UnionBuilder #294
Description
Library Version
1.0.0-RC2
Describe the bug
willAddGraphQLTypeToSchema and didGenerateGraphQLType schema generator hooks are not applied on GraphQLObjectTypes built from InterfaceBuilder and UnionBuilder.
Hooks are only applied if GraphQL types are build using generic TypeBuilder#graphQLTypeOf method. Both interface and union builders attempt to build their implementing objects by invoking object builder directly which does not apply the hooks.
To Reproduce
See SchemaGeneratorHooksTest.calls hook after generating object type
Expected behavior
willAddGraphQLTypeToSchema and didGenerateGraphQLType hooks are consistently applied on GraphQLObjectTypes generated from InterfaceBuilder and UnionBuilder.
