Unknown error uncaught and response generated

[opicodes]

In \Fazland\SkebbyRestClient\Client\Client::executeRequest you can get a failed response like:

<?xml version="1.0" encoding="UTF-8"?>
<SkebbyApi_Public_Send_SmsEasy_Advanced>
    <send_sms_classic>
        <status>failed</status>
        <response>
            <code>10</code>
            <message>URLs in message body are not allowed for untrusted users</message>
        </response>
    </send_sms_classic>
</SkebbyApi_Public_Send_SmsEasy_Advanced>

and in \Fazland\SkebbyRestClient\Client\Client::send the responses array would be:

array:1 [
  0 => Fazland\SkebbyRestClient\DataStructure\Response^ {#1998
    -status: "failed"
    -code: null
    -errorMessage: "Unknown error"
    -messageId: null
  }
]
