After update, redirect back to app/page where you were last on

[jancborchardt]

1. Be in an app or on a settings page
2. Update Nextcloud
3. Refresh and see the update screen → update
4. You’re redirected to Files.

Instead, just like we do for when you need to log in again, you should be redirected to the last app/section you were in. Otherwise you are ripped out of your flow.
