Corrected the travis.yml file

Reordered the commands so comments don't separate the commands (breaks travis otherwise). Corrected the run_tests.sh line. I decided not to put it in its own directory yet. Gazebo path environment is confused otherwise. Should be fixable in the future if we need multiple scripts.
