Subject: Item Views: cancel flicking before a model reset

While the view is flicking, if the content is updated by
a model reset, it gets very confused and creates many delegates
that won't be shown inside the visible area.
Now we cancel any active flicking before the model reset is handled.

Fixes: QTBUG-70742
