    Handle error response for webob>=1.6.0

    WebOb change https://github.com/Pylons/webob/pull/230 changed
    the way in which the error response body is formatted such that
    it's no longer a nested dict. So we have to handle both the
    old convention of an error message key to the response body error
    dict and the new way with just the error body dict.

    This was reported upstream:

    https://github.com/Pylons/webob/issues/235

    But given this was apparently implemented as a long-overdue change
    in WebOb the behavior is not likely to change.
