Stack overflow during configuration load after upgrading from 0.8.2 to 0.9.0

[hydazz]

Describe the bug

After upgrading maddy from 0.8.2 to 0.9.0, maddy run/entrypoint fails during configuration loading with a stack overflow.

The same configuration worked on 0.8.2 without changes. After the upgrade, maddy crashes while loading the config instead of either starting successfully or returning a configuration error issue.

The issue appears to be related to module/pipeline initialisation recursion involving a msgpipeline and target.queue bounce path.

Expected behaviour:

• startup normally, as 0.8.2 did (unless my config is now invalid?)

Actual behavior:

• crashes during startup with a stack overflow while loading configuration

Steps to reproduce

1. Try maddy run with my config, or one thats similar:
   • a msgpipeline used for local routing
   • a target.queue used for outbound delivery
   • the queue bounce path delivering back into the local routing pipeline
   • the local routing pipeline being able to deliver to the queue for some destinations
