RPC naming conventions with default exchange

Hello, after the change on RPC naming conventions (#590) is not possible any more use the default exchange.

I simply tried to configure my conventions as following:

RpcRequestExchangeNamingConvention = (type) => "easy_net_q_rpc"; RpcResponseExchangeNamingConvention = (type) => "";

but this configuration throw an error on IPublishExchangeDeclareStrategy.DeclareExchange:

The AMQP operation was interrupted: AMQP close-reason, initiated by Peer, code=403, text="ACCESS_REFUSED - operation not permitted on the default exchange", classId=40, methodId=10, cause=

At the moment i put a patch on my IPublishExchangeDeclareStrategywith this simple, and ugly 😄 , code:

if (string.IsNullOrWhiteSpace(exchangeName)) { exchange = Exchange.GetDefault(); }

but i think should be better add this behaviour on the RabbitAdvancedBus class.
