Bug description

When a synced directory is renamed in the nextcloud there is a sync issue that can not be resolved.

Steps to reproduce

1. sync a directory
2. rename it in the web interface
3. look at the desktop client and the caused issue

Expected behavior

When changing the name I either expect it to automatically adapt that or to give me an option to reselect the nextcloud dir without having to do a complete resync.

Operating system

Debian and Windows (both have the issue)

Package

Official Windows MSI or app image

Nextcloud Server version

30.x.x

Nextcloud Desktop Client version

3.16.4

Is this bug present after an update or on a fresh install?

Fresh desktop client install

I could reproduce it:

1. create a new folder anywhere (named mine Sync folder to rename)
2. add a new Folder Sync Connection for the new folder
3. rename that folder e.g. via the web interface (new name: Sync folder that has been renamed)
4. the next sync will still try to use the old folder name, discovery fails with 404:

There are two of us testing version 3.16.4, and the other person just reported the problem to me.
I'm not having any problems, but I'm an admin, so that might be why.
