When WiFi on the phone is configured to disconnect when sleeping, KDE Connect cannot maintain permanent connection. This is ok, but it brings a bit more requirements on reconnecting.

When SMS arrives, the phone wakes up and reconnects to WiFi and then KDE Connect reconnects too. Also the notifications are synchronized as expected. But since the SMS arrived before the connection was restored, the notification does not pop up on the desktop. KDE Connect should detect new notifications after reconnecting, not only when notification is created.

Reproducible: Always

Steps to Reproduce:
0. Set wifi in your phone to sleep when not in charger.
1. Let phone sleep and wifi disconnect (it takes few minutes).
2. Receive SMS.
3. Plasmoid reconnects to phone.
4. SMS notification is in the plasmoid's list, but there is no notification about the new notification.
