[Nextcloud 20] Error: Migrate everything from app.php to the Application class

After update to Nextcloud 20 (Beta 3), the following error message is thrown ~once a second:

Still happens now with official Version

I just uninstalled and reinstalled the app and the error does not show up anymore. Will have a look if new image previews are successfully created.
