Apply the additional rotation to be applied to a body also

to the interpolated world transform. This fixes a bug for
rotations that are applied only once, since kart.cpp would
use the interpolated world transform, which is otherwise
not updated till the next time step, resulting in a jump
of the kart rotation.
