Bug description

On my instance I have the App store disabled because I manage my apps using the NixOS module.
The overview in the admin settings shows this endless spinner:

It seems like the frontend doesn't handle the response well:

{"ocs":{"meta":{"status":"failure","statuscode":404,"message":""},"data":{"appstore_disabled":true}}}

This seems valid to me, but the loading spinner never stops/hides.

Steps to reproduce

1. Set 'appstoreenabled' => false
2. Open the admin overview
3. See the network requests, especially the one starting with /ocs/v2.php/apps/updatenotification/api/v1/applist

Expected behavior

The loader should go away, since the compatible app updates can't be checked if the app store is disabled.
