As a workaround, you should set productName in package.json to test-project (or something without a slash).

I made a first cut at fixing this in #455. It’s a bit more involved than you’d think, particularly since there are a lot of files that use the Electron app’s name. (And I want to have unit tests for as much of it as possible.)
