Fixed tests so that they run properly

However, the result is not a working app. The main thing here is I got the tests running and got rid of warnings. I did this all on Ruby 2.1.3

I had to comment one test out because it couldn't figure out how to build 'pkg' but then when I go to build again, I have to `rm -rf pkg` anyway to get the app to build again.

Hope this helps (and sorry I forgot about the topic branch). Started committing on master before I thought it through.
This is the test I commented out, because I couldn't figure out what it was doing.
