This reverts #4155 because that didn't work when running under electron (process.on("exit",...) is not called).

This approach puts a try/catch around the start function in app.js and in utils.js the process.exit(1) calls are replaced with throw new Error("process.exit:1");. The error message process.exit:1 is not evaluated in app.js but needed in the tests.

The short delay is now implemented in the catch block so the systeminformation is displayed.

Looks good! One additional thought: would it make sense to introduce a small dedicated error class (e.g. ConfigError) instead of matching on the "process.exit:1" message string? That might make the intent a bit clearer. No strong opinion though - could also just as well be a follow-up PR.
