* fix(status): remove send usage for private unlink_from_conversations

- make unlink_from_conversations public method
- rename unlink_from_conversations to unlink_from_conversations!
- fix send call on private method in statuses_vacuum and batched_remove_status_service

* fix(feeds_vacuum): replace find_in_batches with in_batches

because active record query results should be a little more efficient than
itterating with map and each. Postgres can grasp such lists of ids much quicker
than ruby can.
Will probably make allmost no difference, but cannot hurt either.

* Make autosuggest for mentions return followed accounts first

This makes it so that (when elasticsearch is disabled) when a user types '@foo' in the compose box, they are first going to get accounts they follow ordered by the ranking algorithm, and then second they will get accounts they do not follow, also ordered by the ranking algorithm.

This makes behavior more consistent with user expectation and also with results when elasticsearch is enabled.
