* Avoid using /wiki/ as both article path and script path.
This looked like a mistake and would prevent catching a
mixup as test failure.
The possibly intended use of this was to detect whether the correct
foreign article path is being used, by being different from the
local one. Test this through a more obviously different value instead,
such as "/foo".
* Remove the unused "dewiki" setting.
* Remove use of production-like setting and use something more
obviously fake instead.
