Fix exception messages

[adam-paterson]

API errors are in the format:

{  
   "code":401,
   "error":"Not Authorized",
   "description":"2017-10-06T08:57:02-04:00, Error ERCDPLTFRM-DNLKUPERR occurred when accessing https://gateway.watsonplatform.net/tone-analyzer/api/v3/tone?version=2017-10-06&sentences=1, Tran-Id: gateway-dp01-307987946 - Invalid UserId and/or Password. Please confirm that your credentials match the end-point you are trying to access. A common error is trying to use credentials from an experimental or beta release against a GA release or vice versa"
}

We need to amend \IBM\Watson\Common\Api\AbstractApi::handleErrors() to account for that format.

I'd like to take a look at this if it's not currently being worked on.

@patrikpihlstrom I’m actually in the middle of refactoring a lot of the foundation classes for the SDK.

If you’re looking to get involved in the project for hacktoberfest I’m happy to write something up for you to work on!
