Akihiko Odaki (@fn_aki@pawoo.net) f85dbe83c8 Remove sort in Feed (#4050)
In from_redis method, statuses retrieved from the database was mapped to
the IDs retrieved from Redis. It was equivalent to order from high to low
because those IDs are sorted in the same order.
Statuses are ordered with the ID by default, so we do not have to reorder.
Sorting statuses in the database is even faster since the IDs are indexed
with B-tree.
