Lipu Fei d662770b22 Fix setting new material for stacks
CURA-4204

When a new material is created during project file loading, the material
for each stack is set according to the parent material ID, but actually
the child material should be used. This fix uses a hack to find the
corresponding child material for a stack so when a user chooses to
create a new material during project file loading, the material can be
correctly set.
