Autosave is not compatible with Folders - New documents cannot be created in folders

Describe the Bug

When auto save is enabled on a collection that supports folders, it causes an issue when you attempt to create a new document from an existing folder. As soon as you start editing the document it will autosave and return you to the folder index.

Expected behaviour: When using Auto save and creating a document from a folder the user remains on the edit page whilst auto save happens in the background.

Actual Behaviour: When the user starts editing they are unexpectedly exited from the edit screen.

This is a minimal repo on the blank create-payload-app, see single change for collection setup here:
https://github.com/tkgdbowen/payload-autosave-folder-issue/commit/e10afb84a434955f6ff4eeeeaf3a5995308f517f

Reproduction Steps

1. Create a new payload app using the website template
   pnpx create-payload-app@latest
2. In payload.config.ts enable the folders feature
   buildConfig({ folders: {}, ... })
3. Enable to folders feature on the pages collection in src\collections\Pages\index.ts, the versions feature is already enabled by default.

   export const Pages: CollectionConfig<'pages'> = {
     folders: true,
     versions: {
       drafts: {
         autosave: {
           interval: 100
         }
       }
     }
     ...
   }
   

4. Run the app pnpm run dev
5. Click Browse by Folder
6. Create a new folder called "Test"
7. Browse in to the new folder
8. Create new Page
9. Begin typing the page Title
10. Observe that the page auto saves as soon as the first character is typed and the user is returned to the folder index.

Reproduce the issue with the linked minimal repository, starting with payload.config.ts and src/collections/Pages/index.ts, then run pnpm run dev and follow the folders and autosave behavior. Done means creating a page inside a folder, typing in it, and remaining on the edit page while autosave runs instead of returning to the folder index.
