Don't override ProjectConfig as Project in schema exports

[Grifs]

Describe your changes

Output the project config under the default name ProjectConfig instead of Project during schema export.

This is now important as the project config is now part of the component config. Previously this was overridden as the class name was ViashProject which was less descriptive.
