### Steps to reproduce

Not entirely sure, TBH.

The problem is that after the excellent work in #16819 to resolve #16818, there is still a strange occurrence.

I was able to quickly (and without having to choose server/local file over and over again -- yay!) resolve a slew of conflicts. But I am left with 7 that don't seem to want to resolve. Or rather, they say they are resolved but do not disappear from the list. In all of these 7, I press on them to resolve the conflict and I get a toast message saying _File not found on local filesystem_ which is very quickly replaced with another toast message: _Conflict resolved_ but the conflict remains in the list.

It is interesting that there is even a conflict registered for a file that exists neither on the local device nor remotely on Nextcloud.

### Expected behaviour

If a conflict is resolved, it should be removed from the list.

But more importantly, why are conflicts even being created for files that exist in neither location.

### Actual behaviour

Conflict continues to remain in conflict list.
