(#24) Removed commands no longer required

Since this is now working, let's remove the commands that were used to figure out where the gem files were located.

Also, as a result of this build:

https://ci.appveyor.com/project/GaryEwanPark/adnuguk-github-io/build/1.0.14

Don't need to include the extra folder location, as there is nothing in there.
