Catch KeyError['empty_material'] when evaluating whether there's any profiles

Browse Source 
This is currently only used in the pre-read of workspaces. In some cases, the project file may have a material that is not compatible with its own stack using the current rules in Cura, either because the rules changed or because the project file is wrongly crafted/edited. This causes Cura to say there are no quality profiles if the material profile is not compatible with the printer, preventing a crash due to the KeyError.
