### Bug description

After upgrading to NC version 32, if `'quota_include_external_storage' => true` was set, share links that share a directory located on an external storage can no longer be accessed.

The user-facing error message reads "This folder is unavailable, please try again later or contact the administration"), see the screenshot:

![Image](https://github.com/user-attachments/assets/90288fe7-465a-47cc-b591-857e4dace1ec)

Debug log is attached below and reports:
`OC_Helper::getGlobalStorageInfo(): Argument #2 ($user) must be of type OCP\\IUser, null given, called in /opt/www/nextcloud/lib/private/legacy/OC_Helper.php on line 278`

### Steps to reproduce

1. Set `'quota_include_external_storage' => true`
2. Add external storage (here: local file)
3. Create a directory
4. Create share link to that directory
5. Open share link
6. Notice the error
7. Set `'quota_include_external_storage' => false`
8. Refresh share link
9. Directory can be accessed


### Expected behavior

Setting `'quota_include_external_storage' => true` does not break directory share links
