simultaneous folder rename on server and client can merge folder contents into one

Seen on windows 10, 22H2 with desktop beta 3.0.0.1960
Seen on ubuntu with OpenCloud Beta 3.0.0.1858

• Connect client to server, wait for initial sync
• Create folder foo with file from_server.txt on the server Web UI.
• Create folder bar with file from_client.txt on the desktop.
• prepare rename of foo to hello on the server, but don't hit enter.
• prepare rename of bar to hello on the client, but don't hit enter.
• hit Enter on both Server and Client.
• Renames happen without error. OKish
• A single folder hello remains, containing both from_server.txt and from_client.txt - BAD.

Expected behavior:

• folder contents never changes while renaming a folder.
• either server or client succeeds to claim the name hello. Normal conflict resolution applies and the other folder is named 'hello (2)'.

Its not a bug, we are syncing files... the outcome here is totally acceptable.
