swiper.el (swiper--action): Set evil search direction to forward #947
Without setting evil-ex-search-direction, evil-search-next and
Without setting evil-ex-search-direction, evil-search-next and evil-search-previous (bound to `n` and `N` in evil-mode) will repeat swiper's last search, but will use the direction of the pre-swiper search. If there is no previous search before swiper, evil-search-next and evil-search-previous will not work. swiper doesn't have a concept of `backward` search, hence it makes sense to always set direction to 'forward.
