[CAY-2202] NPE closing the project

Description

I had a project open in CayenneModeler. After doing some work, I tried switching to another project from "Recent Projects". Got the error below. I dismissed the error, and tried closing the current project instead. Got the same error. I can no longer reproduce it (so this is likely related to the model state prior to closing the project). But perhaps we can guess an issue from the stack trace.
