Added arguments to test launch

Added arguments when launching the test:
 - Added robot ip
 - Added launch_ursim to choose whether or not to launch ursim when running the test.
 - If the arguments are not provided the behavior is the same as before adding the arguments.

Ensure that the scaled joint trajectory controller is running, before sending the motion.
