[3dprinter-general] Bug#1076871: Bug#1076871: cura: FTBFS: AttributeError: 'called_with' is not a valid assertion. Use a spec for the mock if 'called_with' is meant to be an attribute.

It's caused by incorrect usage of mock.called_with and should actually be mock.assert_called_with, which was flagged in Python 3.12: https://github.com/python/cpython/issues/100690

@hroncok has started working on a patch here: https://github.com/Ultimaker/Cura/pull/16103

I'll try to pick this up and see if it fixes the issue on our side.

Regards,
Gregor
