Core/Unit: Ignore On Transport spline movements if the Unit isn't on a transport anymore

On Transport splines use coordinates relative to the transport but if the transport is not found anymore than there is no way to get the absolute coordinates, leading to relative coordinates being used as absolute instead. The result is a Unit being set at position (0, 0, 0) or close by.
