When VisualEditor is not installed, there is no point in registered
resource loader modules that depends on it. A use case is trying to run
tests for the MediaWiki tarball. It comes with Cite but without
VisualEditor.
The patch is based on GuidedTour patch by Matthew Flaschen
https://gerrit.wikimedia.org/r/#/c/305691/ for T143297

The current path for the test files was wrong and broke qunit test
running in debug mode. This fix corrects the path for both debug
and non debug mode.
