Fixes blocking error about "missing time_from_start" with non-JointTrajectoryPoint start point when running trajectory_test.py. Fixes trac 7657

Uses a default JointTrajectoryPoint with p1.positions set, where there was just a list of positions stored to p1 directly before.
Also, typo minor fix (I believe) in the parameters. @rethink-kmaroney should check me on this.
