Provide response body when exceptions are ignored

Normally, exceptions are thrown on HTTP errors (404, 500, etc).
If the user chooses to ignore these exceptions with the `ignore`
parameter, the response body was entirely empty.

This commit returns the full response body from the server so that
the user can parse it as required.
