Fixes https://github.com/status-im/status-desktop/issues/12558
When getting kicked out of a community, before we used to leave the community completely, but just keep the filters on.
That created a problem when reopening the app, because the community disappeared and could even create a problem in desktop where it tried to open the last opened community but it's no longer there.
The fix now is that when getting kicked out, we instead just remove ourselves from the community and set Joined to false, but we keep the community spectated.
chore:
- add CommunityEventsMessage
- refactor community_admin_event to accept a list of events and patch a CommunityDescription
- save/read community events into/from database
- publish and handle community events message
- fixed admin category tests
- rename AdminEvent to Events or CommunityEvents
