Append query string + fragment to javascript: url.

Browse source 
When loading a URL whose scheme is javascript, we should do what
https://html.spec.whatwg.org/multipage/#javascript-protocol
says and append the URL's query and fragment components to the scheme
data, as well as percent- and utf-8-decode the whole thing, before
evaluating it as javascript.
