Small fixes to get the TextTest tests working

I've been checking out the GildedRose kata in anticipation of running it as a dojo session.  I've found a couple of wrinkles with the tests for python and ruby - you changed the code to be more like the C# original recently, but I guess the changes to the tests didn't make it to the repo.

I've also removed the dependency on the CppUTestExt lib for building the C implementation.  When I grabbed and built CppUTest 3.3, it didn't make this lib, but it does not seem to be used.  Removing it allows everything to work fine.
