Fix crashing when material could not be found

Browse Source 
See CURA-3M in sentry. It most commonly happens with the anycubic,
since it had some weird stuff with it suddenly supporting materials.

This change will make it so that no crash happens. Old profiles will still have
an empty material. This isn't really an issue, since the interface will mark this
as an error (prompting users to switch).
