Rust bindings do not output import statements for enums when expected

[krisbitney]

Describe the bug
In an imported module that uses an enum, Rust bindings are being generated without the required import statement.

The import statements are missing in wrap/imported/concurrent_module/serialization.rs.

Expected behavior
I expected the following at the top of wrap/imported/concurrent_module/serialization.rs:

use crate::{
    ConcurrentReturnWhen,
    get_concurrent_return_when_value,
    sanitize_concurrent_return_when_value,
    get_concurrent_task_status_value,
    sanitize_concurrent_task_status_value,
};

Please provide the steps to reproduce and if possible a minimal demo of the problem.
