[Bug]: Checksum recorded in file cache not copied when file is copied

[patrick-stickler-csc-fi]

⚠️ 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

When a checksum is recorded in the file cache for a file, that checksum is not included in the file metadata that is duplicated for the new file cache records when the file is copied. Size, timestamps, mime type, etc. are all duplicated, but not the previously recorded checksum.

Steps to reproduce

1. Upload a file using a client that reports the checksum of the file on upload.
2. Copy the file to another location within Nextcloud using either the UI or WebDAV.
3. The file cache metadata for the new copy does not include the previously recorded checksum.

Expected behavior

The file cache metadata for the new copy would include the previously recorded checksum.
