Files_reminders app doesn't load, and no error is shown if the notification app is not installed. #49231

Hello everyone,

Files_reminders app depends on the notifications app. The issue is with the Files_reminders app failing to load silently when the notifications app isn't installed.

The app doesn’t return feedback when the Files_reminders is enabled but fails to load, meaning users won’t realize that there’s an issue unless they check manually for the notifications app. This is an annoying issue, particularly for admins who need to compile from source to make customizations for their instances.

Steps to reproduce

1. Clone nextcloud master and compile.
2. Enable Files reminers app
3. Check file context menu (popover) and, you'll see that set reminder is missing.
