.travis.yml: Go back to "catkin run_tests"
.travis.yml: Go back to "catkin run_tests"

"catkin run_tests" prints the full output, which "catkin test" doesn't.
The previous commit message was wrong: "catkin run_tests" actually runs
all tests, but it always returns 0. Adding catkin_test_results fixes
this.
