Messages not being acked after being processed

Hi guys,

We are using Hutch to listen to a routing-key on RabbitMQ and insert the read message on ElasticSearch.

We found out some strange behaviours that we don't know if it is expected.

A batch processes publishes messages and we are facing the following:

Our code is nothing more than:

module ElasticsearchSync::Worker
  class MyClass
    include Hutch::Consumer

      consume 'a_routing_key.*'
      queue_name 'my_queue_name'

      def process(message)
        // Posting to ES
      end

  end
end

As you can see, the messages are not acked after being processed.

The Hutch's version is hutch (0.19.0)
