Subject: [PATCH] =?UTF-8?q?fix(whatsapp):=20restaura=20attachment=5Fparams?=
 =?UTF-8?q?=20no=20PayloadParser=20para=20m=C3=ADdia=20funcionar?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

O refactoring c48047ba5 removeu attachment_params acidentalmente sem mover
para outro lugar, quebrando o download de áudio, imagem, vídeo e documento.
O método é chamado por incoming_message_wuzapi_service.rb#attach_files.
