Listen to intents to restart service on app upgrade/phone reboot

In brief

• If previously connected to core, Quasseldroid should restart the service on app upgrades and device reboot
  • • Android 8.0+ send a broadcast MY_PACKAGE_REPLACED, while earlier versions send PACKAGE_REPLACED; both versions send ON_BOOT_COMPLETED
  • This would be similar to KDE Connect's handling
