improve local status updates (#3480)

The idea here is: Everytime we get hold of a new version of a post, we
update everything about that post everywhere.
This makes the distincion between different event types unnecessary, as
everythng is just a `StatusChangedEvent`.
The main benefit is that posts should be up-to-date more often, which is
important considering there is now editing and #3413
