The MaterialManager.materialsUpdated signal was only called once upon init and for the rest when a favourite was added or removed. So only the FavoriteMaterialsModel would need to listen to it. Because the MaterialManager is being deprecated, the favourite materials model now just listens to the preferences changing instead, as it was supposed to be doing anyway. Contributes to issue CURA-6600.
