added spec for expected headers when error raised

When we set headers using `before`, `after` or just before `error!` raised, we expect them to transferred with error response together.

* First spec will be `success` due to there is no error.
* Second test will fail at the moment because when an error raised, all headers will be ignored. They shouldn't be.
