      Description

      As per Gordon's description:

      If a given queue is bound to a topic exchange with multiple bindings, a message sent to that exchange will result in a copy being enqueued for each binding that matches. This is incorrect - each message should be enqueued once if there is any binding to the queue that matches it.

      Steps to Reproduce:
      1. create queue
      2. bind it to amq.topic with two distinct bindings (e.g. red.* and *.herring)
      3. send amq.topic a message whose routing key matches both patterns (e.g. "red.herring")
      4. check the queue

      Actual results:

      The message is enqueued on the queue twice.

      Expected results:

      The message should only be enqueued on the queue once.
