Stack overflow during configuration load after upgrading from 0.8.2 to 0.9.0

# 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

# Log files
```
