Kaminari 0.14.1 in 1-3-stable

I found myself in need of this update in a project where is not viable to upgrade to 2-0-stable at the moment.

According to [spree/spree#2169](https://github.com/spree/spree/pull/2169), this breaks the API specs. This pull request introduces the same changes as https://github.com/spree/spree/commit/a1f3f21ef1abb1fdbdcbd7ac8fb50e0e704f3c81.

Not sure whether these changes are welcome in this branch given the spec breaking but thought this could also be useful to others.
