change_speed request not working

[alexdawn]

Running the whole stack using the simurgh dockers. I found in the example scenario I was unable to change the vehicle speed with change_speed, the target vehicle would continue with the same speed, the command did not fail as no exception occurred. Likewise using the twitcher UI trying to change the speed also would not work.

I instanced a new vehicle using the dodo command, and again I found I was unable either via dodo or twitcher to change the vehicles speed.
