Migrate the remaining XyzList controllers

[gpunto]

Goal

Same as #87, but for FollowList, CommentReplyList, MemberList, PollList, PollVoteList, ActivityList. With this, the only things left to migrate are Activity & Feed.

Implementation

Change handler from WSEvent to StateUpdateEvent

Testing

Nothing should change externally, as here we're just consuming WS events using different types from before, but not emitting events from new places (yet).
