Update .travis.yml to send test coverage (#9)

This changes updates the format of the travis.yml to match our general format, as well as ensuring it is configured to send test coverage stats to codeclimate.

It also makes a tweak to the `simplecov.rb` rspec support file because we noted that coverage wasn't working.

We had used this config in other repos and still been able to generate coverage, however in this repo it causes simplecov to return LOC 0 with a coverage score of 100%!

This took way too much time to track down, so we are simply blitzing the offending line and moving on.
