Items API returns a type of "Video" for movies in a collection

[heyhippari]

Describe the bug

When calling the Items API (/Users/<user_id>/Items or /Items), the API returns the wrong type for the items.

Movies get the type "Video", which causes them to lose all metadata information in the web client (Posters, titles, etc).

System (please complete the following information):

• OS: Arch Linux
• Virtualization: None
• Clients: Browser
• Browser: Firefox 74
• Jellyfin Version: 10.5.3
• Playback: n/a
• Installed Plugins: None
• Reverse Proxy: Nginx
• Base URL: none
• Networking: n/a
• Storage: cloud

To Reproduce

• Select multiple items
• Add them to a collection.
• Query the API to get the collection's children

Expected behavior

The API should return the proper information for the items as if they were part of a library, to allow the proper display of metadata on clients.

Additional context

Seems like some items are affected while some are not. Not sure of a proper way to replicate yet.
