rCOMMdc850ca7e1ef: [lib] Move calendar filters update reducer into specs

Summary

Changed a solution slightly. Instead of mutating a set for each update, we're creating a new one, which might be less performant, but is better for maintainability.

Depends on D9296

Test Plan

Bring back the old code and check if it produces the same result while handling delete, join, or update thread update.

lib/reducers/calendar-filters-reducer.js
142–146	Maybe we can make this logic here more consistent with other `reduce` from previous diffs, but don't have a strong opinion on that.
149	This also makes sense in a way it is, but just want to make sure, is the operator `!==` intentional and better than `_isEqual` in this case?

Make the approach more consistent

lib/reducers/calendar-filters-reducer.js
142–146	Makes sense!
149	Each of the reducers returns the original object if the update doesn't change it, so it makes sense to check just the references. The result should be the same, but the current approach is less wasteful.
