This release fixes a bug with the jekyll-redirect-from plugin. When
using the `redirect_from` option it provides, `jekyll-algolia` was
trying to index non-existing files and throwing errors. We now exclude
any file that has its layout set to `redirect`. It solves potentially
wider issues than just `jekyll-redirect-from`, because we assume that
a layout called `redirect` means that the page is only here for
redirection and doesn't need to be index.

We also disable the `autopage` feature of `jekyll-paginate-v2` as it is
also creating new pages that don't contain any content worth indexing.
