Offline upload conflicts resolution overwrites the remote file even if the user select to keep both

⚠️ Before posting ⚠️

• This is a bug, not a question or an enhancement.
• I've searched for similar issues and didn't find a duplicate.
• I've written a clear and descriptive title for this issue, not just "Bug" or "Crash".
• I agree to follow Nextcloud's Code of Conduct.

Steps to reproduce

1. Create a folder
2. Upload a file (e.g. a text file)
3. Go offline (e.g. airplane mode)
4. Change the file (e.g. add some characters)
5. Upload a second time the file
6. Go online
7. A conflict message is shown
8. Choose to keep BOTH files
9. The online file is overwritten by the new uploaded file (only one file present in the folder at the end)

Expected behaviour

The folder should contain two files: the remote one and the newly uploaded, renamed (as it happens if following the same steps without ever going offline).

Actual behaviour

The online file is overwritten by the new uploaded file (only one file present in the folder at the end)

Additional information

I think it's related to ConflictsResolveActivity having its own flow for offline uploads (see showOfflineOperationConflictDialog()) and passing Decision.KEEP_BOTH_FOLDER instead of KEEP_BOTH to the worker
