When a response is not 'ok', an event 'server-error' is fired with the response as argument. If an error handler reads the text content of this response, it cannot be read again in following call to 'getResponseObject'. If we try to read it again, it will lead in an error 'Already read' and the event 'network-error' will be fired because of this. This issue can be reproduced with executing an invalid change query. The meaningful error message will be hidden directly with a generic error message 'Server unavailable'. Change-Id: Iffa85c2762a965f5f55fcb7041ea5fad4ed4f475
