fix: use the Logger passed in RabbitMQModule config instead of default

[lucas-gregoire]

Hello, I discovered an issue when passing a custom Logger to the RabbitMQModule:

Some logs are made using the logger passed in the config:

But some other logs, like ones written in onApplicationBootstrap, don't use the Logger provided in the config but the logger property of the RabbitMQModule which is not configurable.

---

So my fix consists of using the logger from the provided config everywhere in the RabbitMQModule.
And now all logs are correct:
