Throttle Exceeded error incorrectly reported

When QuickBook’s rate limit is exceeded the client receives the error response but raises the exception for when it cannot read the json response instead of reporting that the request limit has been reached. Provided below is the exception thrown when this occurs:

QuickbooksException: Error reading json response: <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<IntuitResponse time="2016-10-10T12:14:28.801-07:00" xmlns="http://schema.intuit.com/finance/v3">
    <Fault type="SERVICE">
        <Error code="3001">
            <Message>message=ThrottleExceeded; errorCode=003001; statusCode=403</Message>
            <Detail>The request limit was reached.  Try again later</Detail>
        </Error>
    </Fault>
</IntuitResponse>

It looks like this is happening because the make_request method in the QuickBooks object expects both success and error response to return json but for the ThrottleExceeded error QuickBooks responds with xml.

I am using version 0.5.1 of the library and a sandbox instance on QuickBooks.

According to Intuit the Requesting json, receiving XML errors issue has been fixed.

Small update on this from QuickBooks. The throttle error is handled by their Gateway service layer and they have filed an internal issue to address this bug. I will provide any updates from QuickBooks as I receive them.
