Fix fetching referenced resources from List resource when working with (local) configs from the assets directory

[ellykits]

Describe the bug
When running the app with local configs, the referenced resources in List are not synced down when the Composition section items are downloaded.

To Reproduce
Steps to reproduce the behavior:

1. Create and post a ListResource that references Medication resources to the server
2. Reference the List in the Composition resource in the local assets directory
3. Trigger sync
4. Observe that the referenced resources in the ListResource are downloaded/not downloaded

Expected behavior
All the referenced resources in the List should be downloaded when the Composition section resources are synced.

Additional context
Please look over how the referenced resources in the Composition resource are downloaded.
