@PostConstruct in DefaultBulkApiService does not work

PostConstruct does not execute using spring boot (1.4.1) which therefore means that the validator is never initialised;

e.g. this is not called

@PostConstruct
private void afterConstruct() {
   this.validator = new BulkApiValidator(this.appCtx);
}

As a result all bulk operations fail with an error code;

  "status": 500,
  "error": "Internal Server Error",
  "exception": "java.lang.NullPointerException",
  "message": "No message available",
  "path": "/bulk"
}

This is because the bean is not managed. Extended the service works as per com.github.wnameless.spring.bulkapi.test.AppConfig
