Fixed Todo e2e test suite

- Updated Todo e2e test suite to work with AngularFire 0.8 API
- Improved protractor error reporting
- Removed option in Travis file which only ran Travis in the master branch
Yes and no. It's not what we want ultimately, but I wanted to only run the todo app to see if it would pass in Travis. I'll make sure to put this back to the old glob in a future checkin. Nice catch!
