Adds the previous_url helper as described in #1025
Description
If the Referer header is set, this method should return the url from the header. A user should pass a Lucky::Action or Lucky::RouteHelper as a fallback in instances where the Referer header is not set.
Functionally, it works very similar to the redirect_back method added in #1168 but is suitable to use within a Lucky::Page
