Fix scoped overlay use not finding a module (#6474)

* Add source-env test for dynamic path

* Use correct module ID for env overlay imports

* Remove parser check from "overlay list"

It would cause unnecessary errors from some inner scope if some
overlay module was also defined in some inner scope.

* Restore Cargo.lock back

* Remove comments
