* [Automower] Fixed consts with channel ids after removal of channel
groups. Improved the mower state update:
- Cache the last read state from API
- Use cached mower state so the items linked will always be up to date
  without the need to wait for API refresh period.
- Use timeZoneProvider to user user set timezone.
