Don't crash when importing definition files as materials

Browse source 
Reproduction steps:
* In the Material Manager, click on 'Import material'.
* Change the file type in the file dialogue to 'All files'.
* Select any .def.json file, for example from Cura's own resources/definitions folder.

Previously this crashed the application. Now it shows the user an error message instead.

Fixes Sentry error CURA-D4.
