JTC trajectory end time validation fix #1090

The time_from_start member for a JointTrajectoryPoint is monotonically increasing, not a delta time, so I think we can just use the last one in the vector; summing them up seems incorrect. I also moved the points empty check earlier because .back().time_from_start would seg fault with an empty points vector.

Could you please check the docs if this is clearly documented how to fill the trajectory field? Here is a comment, but maybe we should add this in a more prominent place.

That page seems clear to me, the plots in there are very helpful. Perhaps it should be in the main JTC page, but where it is seems fine IMO.

LGTM. Just one request: Could you please add checks for the end time to invalid_message test?
