Sander/add config to handled route (#206)

* fix(behaviour of postrender array): makes sure the postreder array is passed correctly

<ake sure it doesn't throw out the defaults if no specific route postRenderes are configured. Also
pass the config into the handledRoute

* feat(index.ts): export httpGetJson helper from scully
