charging: Move event catch to appropriate place and tweak setting

- Charging profile prepared but not included (most likely not needed)
- Charging prio kept with slight delay to catch some timing issues

Note: Workaround not perfect but catches most cases where connecting
      barrel plug would make charging prio setting jump to charge battery
