Autocomplete view-source URL

User may miss the URL scheme (eg. http://) when type a view-source url
into the browser's location bar (eg. view-source:qt.io). This is not
handled by the Chromium thus will produce an empty view-source page.
The new autocompletion extends the incomplete view-source URL thus it
will provide valid URL if it is possible (eg. view-source:http://qt.io/)
