Remove optimisation that broke updates of models upon metadata change

Browse source 
If the metadata changed, such as whether a material was favourite or not, then the materials models were not updating any more because the actual list of available materials was still the same.
I've removed this optimisation and tested performance locally. It seems to be slightly slower (though that might be placebo or measurement error). However most of the performance boost of cura-6016 was resulting from different changes there so the interface still seems to be quite a lot faster than what it used to be.

Contributes to issue CURA-6032.
