[Desktop] Sync v2 - Inconsistent bookmark structure after moving a bookmark to just deleted folder

[btlechowski]

In a rare situation when user deletes a folder on one device and then on the other device will move a bookmark to said folder, the bookmark structure becomes different on the devices

Steps to Reproduce

1. Clean install on DeviceA and DeviceB
2. Establish sync chain between DeviceA and DeviceB
3. DeviceA: Add bookmark folder FA1
4. DeviceA: Add bookmark A1
5. Wait for sync update
6. DeviceB: Delete FA1 and the same time on DeviceA: Move A1 to FA1
7. Wait for sync update

Actual result:

Inconsistent bookmark structure.

Note: Next sync update does not fix the issue
Note: Browser restart does not fix the issue
Important: opening the orphaned bookmark fixes the issue, the bookmark is synced to another device

Expected result:

The same bookmark structure
