Reduced the amount of events Collections listens on

refs https://github.com/TryGhost/Team/issues/3169

- When a not yet mapped event is produced by Ghost model the posts belonging to a collection are recalculated in a brute-force way. This causes a lot of strain on the database and times out some of the tests. Right now we only care about a handful of events, so limited the ones we listen to and will be uncommenting the rest when we have an optimal mapping/handling for them.
