[Bug]: ScanFiles job triggers a scan of the root storage for each and every user #61510

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

• The ScanFiles background job tries to scan the entire root storage along with the home storage of each user it detects as unscanned
• This includes the appdata folder and it scans these for each and every user once
• This can lead to extremely long running jobs (>24h sometimes)

Steps to reproduce

1. Have a few unscanned entries in filecache table for your user and also for the appdata folder
2. Trigger the ScanFiles background job

Expected behavior

• Each user with unscanned files should be scanned and not the root folder which contains appdata directory
