Recursive bundling tries to import submodules

[maximebuyse]

mod a {
    pub fn f () {
        super::b::i()
    }
    pub mod aa {
        pub fn g(){}
    }
}

mod b {
    pub fn i() {super::a::f()}
}

Open this code snippet in the playground

In the generated code for module a we have include Playground.A.Rec_bundle_927482861 {aa as aa}. This shouldn't be here and doesn't lax-check.

The fix for this should be similar to #1030
