fix(timeout): do not reset steer wheels to 0. on timeout

[reinzor]

Instead of setting the incoming twist command velocity to zero, we should only set the wheel commands to zero without altering the steering angles in order to avoid in-place steering of the wheels.

This makes sense to me, thanks for the contribution.
Could you please have a look on the failing tests and change the assertions accordingly?
Please add also a short description in the release_notes.
