Add TrackingId to ApiError message.

[sQu4rks]

Since the tracking id is a great way for the support team to troubleshoot issues what do you think about including it in the error message of the ApiError?

While you can access it via the response property of the ApiError this option is only accessible when actually catching the error.

Great idea. This will definitely help improve the transparency of the API responses and errors.

I'm on it, and I'd love your feedback. I'll submit a PR for you to review.

I just merged the PR. Closing this issue.
