Filter is reset, if autoqa error is marked as false positive

If you set a autoqa filter (for example only show segments with spelling errors) and you then set an error to false positive (be it with the segment open and in the right panel or with the segment closed with a right click) the filter is reset.

This should not happen. Please analyze first together with Axel, why this is implemented like this so that the fix does not introduce a new bug, because this probably has a reason.
