Race condition when saving/syncing

[juliusknorr]

I have a report with a har file dump for a shortly popping up conflict dialog that seems to be caused by a race between the save and sync request where both are issued roughly at the same time but the save happens and therefore the sync returns a temporary conflict

First and second request have the same version in the request data:

This happens more often and was reported internally a lot

Needs some time spending on trying to artificially cause it to see in which scenario we might run into this on slower requests.
