Description

Leaving out the exchangeName i.e. rabbitmq://localhost/ throws exception below.

However RabbitMQ has the default exchange "" so it's not required to specify amq.direct explicitly., and this makes it impossible to send to that exchange (which is different than amq.direct).

Should have been fixed by CAMEL-7031 (2.12.3) but still happens in 2.14.1 (probably regression)
