The main thrust of this PR is to take all the conditional checks based on the `enable_bookmarks_with_reminders` away and only keep the code from the `true` path, making bookmarks with reminders the core bookmarks feature. There is also a migration to create `Bookmark` records out of `PostAction` bookmarks for a site.
### Summary
* Remove logic based on whether enable_bookmarks_with_reminders is true. This site setting is now obsolete, the old bookmark functionality is being removed. Retain the setting and set the value to `true` in a migration.
* Use the code from the rake task to create a database migration that creates bookmarks from post actions.
* Change the bookmark report to read from the new table.
* Get rid of old endpoints for bookmarks
* Link to the new bookmarks list from the user summary page
* 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!
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
This should only change the order on freshly imported instances with no likes.
This makes the user summary show the latest topics/posts/links instead of the firsts until the users get some likes.
Added "Top Links" list
Added "Most Liked By" list
Added "Bookmark count" stat
UX: Use fa heart icon instead of "like" text in stats
Change the order of the user stats
