Bug description

When using Nextcloud desktop client 3.17.4 or 4.0.4 + server 32.0.3 + Clamav, files larger than 2gb or so, the client upload the files twice, but there's no file duplication. I observed these steps:

• New file is added to synced folder
• Client analyze the file
• Client starts chunck upload, which can be seen on user upload folder
• Client finishes upload
• Server pass files to Clamav to scan
• Clamav finishes scan
• Server finishes mounting file
• Client starts new syncing
• Client uploads the same file again (I can see new folder inside user uploads)
• Client finishes syncing

If I restart nextcloud client after server finishes mount the final, the last steps aren't executed and it says it's synced. It's seems while files being scanned the client thinks it needs to upload again, idk

Steps to reproduce

• New file is added to synced folder
• Client analyze the file
• Client starts chunck upload, which can be seen on user upload folder
• Client finishes upload
• Server pass files to Clamav to scan
• Clamav finishes scan
• Server finishes mounting file
• Client starts new syncing
• Client uploads the same file again (I can see new folder inside user uploads)
• Client finishes syncing

Expected behavior

After file scan and finishes mounting it should not trigger another upload
