Wiki update 1.0.2 to 1.0.4 installes wiki lite as second instance

The timing was just perfect. I installed Wiki 1.0.2 today and was instantly notified about an available upgrade to 1.0.4.

The upgrade however created a second instance of Wiki in the plugins directory, what on closer inspection turned out to be the "Lite" version. So Wiki 1.0.2 still insists on an upgrade...

Just to let you know...
