Fix swiper "backward" search

* ivy.el (ivy-recompute-index-swiper): When none of the previous
  candidates after the point match the current input, instead of
  returning 0, return the index of the last matching candidate.  This is
  a good choice, because that candidate is the closest to the point of
  the initial search start.

Fixes #319
