Add queue options to producer

Hi Jose!
This is the first day that I play around with rabbitMQ and so I´m not finally sure if I´m using the service provider wrong or wether this is a bug. By using your version all messages are sent to rabbit in anonymous channels (amq.gen-foobar). When I add my options via setQueueOptions to the producer (like it is done for the consumer) all messages are sent to the channel from my options as expected.
