How to test

1. First increase version in applications/electron/package.json to e.g. 1.39.1
2. yarn && yarn electron package
3. Copy applications/electron/dist directory to some other location
4. Run npx serve -d -u -p 5000 in the copied dist directory to serve this build as a potential update
5. Undo the change from step 1
6. Update the urls in applications/electron/electron-builder.yml to http://localhost:5000
7. Run yarn && yarn electron package again (this time building an app with version 1.39.0)
8. Start the built 1.39.0 application and check whether the update works again.
