Bug description

When opening/reloading the maps page while not logged in, it shows an internal server error (instead of redirecting the user to the login page).

While this may be less problematic on a desktop in a real browser, it can be highly annoying on an Android device when adding Nextcloud Maps to the home screen as a shortcut (via "Add to home screen" in Firefox), in this case there is no location bar and there is no direct path for the user to go back to the main page and log in. The only way of recovery is opening a real Firefox window, navigating to the Nextcloud URL and logging in there, after that the home screen shortcut will continue working.

Here is the entry from my nextcloud.log:

Steps to reproduce

1. Go to Nextcloud Maps
2. Copy URL and re-open it in a private window
3. Resulting page shows this internal server error, with no way to log in without manually navigating to the main Nextcloud URL.

Expected behavior

The Maps app should redirect to the login form when the user is not logged in.
