`:mvn/local-repo` isn't propagated in some cases

[zelark]

Describe the bug
When :mvn/local-repo is set in user deps or provided via -Sdeps, it isn’t propagated correctly.
Only root dependencies are downloaded into the :mvn/local-repo path.

I saw #532 and hoped it would fix the issue, but unfortunately it didn’t.

To Reproduce
Steps to reproduce the behavior:

1. Navigate to examples/local-maven-repo
2. Check out the 0.22.2 tag
3. Comment out or delete :mvn/local-repo in ./deps.edn
4. Add a dependency in components/stuff/deps.edn, for example: nano-id/nano-id {:mvn/version "1.1.0"}
5. Run clojure -Sdeps '{:mvn/local-repo "./maven-repo"}' -M:poly test :dev

Actual behavior
nano-id is downloaded into ~/.m2/repository/

Expected behavior
nano-id should be downloaded into ./maven-repo. In general, all project dependencies (bases, components, etc.) should be downloaded into the same ./maven-repo directory.

Additional context
Setting :mvn/local-repo in ~/.clojure/deps.edn also doesn’t work.
