FIX: Minor bookmark with reminder issue cleanup (#9436)

* Count user summary bookmarks from new Bookmark table if bookmarks with reminders enabled
* Update topic user bookmarked column when new topic bookmark changed
* Make in:bookmarks search work with new bookmarks
* Fix batch inserts for bookmark rake task (and thus migration). We were only inserting one bookmark at a time, completely defeating the purpose of batching!
