Steps to reproduce

1. Use a mobile browser (Safari, Chrome ...)
2. Try opening a link like [[wikipedia:de:Test]] (foreign wiki, foreign language)
3. Let the browser open the link with the Wikipedia App

Expected results

The linked article should be opened like always.

Actual results

There is an error message: "The page you specified doesn't exist."

This happens because the interwiki links generate links like " http://en.wikipedia.org/wiki/de:Test ".

The App code seems not to like the "de:Test" part. If there is no "de:", the link works properly.
