RabbitMQ: Disposing Iconnection Imodel earlier than we should

[ElectNewt]

When consuming messages we work with Iconnection and IModel both of them are IDisposable but inRabbitMQMessageConsumer.consume they were being disposed before the message was processed, which caused that we couldnt update the message to processed.

The current solution its not ideal, it works as long as the app does not scale crazy, but it has to be fixed.
