Feature/server errors

[Jonesy]

Description

All failed API calls were returning error objects with no content from the response object. This PR removes all the extraneous nested Error objects. When errors are returned the async function will now throw an object with the following structure

interface ErrorObject extends Error {
  status: number;
  statusText: string;
}
