send sms errors

[balbesina]

Smspartner has incorrect documentation for errors.
Each time I receive the error it is not inside body['error'], but in the body['message'].

#<Smspartner::Response:0x0000557ce58baaf8 @success=false, @errors=nil, @code=10, 
@message_id=nil, @raw_data={"success"=>false, "code"=>10, "message"=>"Clef API incorrecte"}>

#<Smspartner::Response:0x0000557ce59416c0 @success=false, @errors=nil, @code=44, 
@message_id=nil, @raw_data={"success"=>false, "code"=>44, 
"message"=>"L'emetteur (ModuloTech123123) n'est pas valide. Il ne doit pas contenir de caractères spéciaux"}>
