Problem description
For phetsims/qa#838.
When a sim is launched, the step back time control is available. However, it "steps back" to the location it was at when launched. If the sim is paused, this should mean nothing happens. However, the orientation of the object is changed.
Steps to reproduce

1. Go to the Model screen and the Planet and Satellite scene
2. Play the sim briefly
3. Pause the sim
4. Launch the sim
5. In the launched sim, hit the step back button and observe the satellite

Thanks @KatieWoe.

@samreid this looks like a problem with the rotationProperty of the object. It's easiest to observe with the satellite, but it's a general problem.

Here's an example following @KatieWoe's steps to reproduce, but with the PlanetMoonScene.

rotationProperty = -1.92... radians in Studio and the initial configuration of the Standard PhET-iO Wrapper:

rotationProperty resets to zero when pressing the Restart button in the Standard PhET-iO Wrapper:

It seems like the rotationProperty is excluded from the state saved by the Restart button, which may explain why the button is enabled by default in the Standard PhET-iO Wrapper. I would expect it to be disabled because the initial state in the wrapper should be identical to the state restored with the Restart button.

I compared to the 1.5 version, and the Restart button is disabled in the Standard PhET-iO Wrapper, as I would expect. However, if you play or step forward to enable the restart button, and then press restart, it will restore a state with the rotationProperty = 0.

Fixed and ready for cherry-pick

This seems fixed in RC.3
