Previously the link on the error page was only linking to the path
component of the url, e.g. `/search` but ignoring any query params e.g.
`/search?q=hello`. This uses the HTTP::Request `resource` method which
appears to capture both.
Instead of showing the default Lucky error page, the styles now match
Scribe. In addition, if a URL can't be parsed, Scribe gives some
information as to why this might be (that Scribe can only deal with an
article pages)
