Throw ApiException for requests with the user's token too

Requests with the user's token threw a bare ResourceException with a
message like "… for resource [Anikeen\Id\Resources\Order]" and no
error code, while app requests threw ApiException. Both throw
ApiException now: status (also getCode()), Anikeen ID's error code and
message, isNotFound(), isConflict(), isTemporary(). Failed lists throw
CollectionException, now a subclass of ApiException. A request without
a response (connection refused, timeout) throws ApiException with
status 0 instead of a Guzzle exception.

ApiException extends ResourceException, so existing catch blocks keep
working.
