Wrong handlers get called if only one queue is used

[webhet]

If a configuration with only one queue is used, all handlers are called if any message is published.
If no queue is defined, the implementation creates a new queue per topic/handler and everything works fine.

The issue probably has to do with how the routingKey is passed on to the callback in amqp/subscriber.ts. If this were to pass on the routing key of the received message (msg.fields.routingKey) instead of the routing key that is passed into the subscribe function (and with which the binding is created) only the handlers for that specific routing key would get called.

The configuration I'm using:

new AMQPPubSub({
    connection: conn,
    exchange: {
       name: 'pub_sub_exchange',
       type: 'topic',
       options: {
         durable: false,
         autoDelete: true
       }
     },
     queue: {
       name: 'pub_sub_queue',
       options: {
         exclusive: true,
         durable: true,
         autoDelete: true
       },
       unbindOnDispose: false,
       deleteOnDispose: false,
     } 
  })
