[assets] Fix AssetServer::get_handle_path (bevyengine#2310)
Browse files Browse the repository at this point in the history
# Objective

- Currently `AssetServer::get_handle_path` always returns `None` since the inner hash map is never written to.

## Solution

- Inside the `load_untracked` function, insert the asset path into the map.

This is similar to bevyengine#1290 (thanks @TheRawMeatball)
