When trying to debug why the tests broke for https://github.com/MichMich/MagicMirror/pull/2946 I found that the tests does not wait for the app to start and close. So if the startup isn't blocking that would fail. So I added a callback for `close()` too and converted them to promises for the `startApplication()` and `stopApplication()` and updated all the e2e tests to await both. Will try to refactor all these callbacks to promises in a later PR.
