Upgrade Smartling API Commons

[dlyash]

Got an error:

com.smartling.api.sdk.exceptions.SmartlingApiException: Response hasn't been parsed correctly [response='{
 "response": {
 "code": "NOT_FOUND_ERROR",
 "requestId": "7bc3e3cb-d701-47ee-a2a1-2773fb2d18ce",
 "errors": []
 }
}']

As far as I see, ResponseCode enum does not contain NOT_FOUND_ERROR.
