fix(moving platform): end the subcomponent list with a 0 bit

The client reads a moving platform's subcomponents while a 1 bit comes
before one (LWOMovingPlatformComponent::Deserialize), as live wrote them.
DLU wrote the mover without the closing 0 bit, so the client took the next
component's first bit for it.
