Endless loop on configuration problem

[judgej]

I think this loop was more a problem in the Laravel framework, but this package can at least check the configurarion to help prevent it.

Some details to be confirmed, but it looks like if message flow has a queue connection defined for outbound messages, and that queue connection is defined in config.queues.connections, then Laravel goes into a fast loop trying to load the config, failing on finding a null, then immediately trying to load the config again as a result.

This was Laravel 8.
