[#169] added ErrorResponse type used as "reject" reason in order to…

… access status code together with body

* fixed that only JSON was assumed as body - fall back to any value if error response was not JSON
* updated dependencies to its minor version updates
* update to upcoming Ditto JS client version 3.0.0
