* 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. * Fix ranking order to correct direction * One more fixup per @gargron suggestion * Tweak to ranking to no longer include following modifier
