TeleportAction sets lane assignments of entities

The current implementation of the teleport action (branch existing_open_scenario_engine) accidentally sets the lane assignments for the teleported entities. This seems to be flawed, as it should not be the responsibility of the engine to update the assignments.

I guess these lines can be removed, but should be checked before.

auto lane_ids = environment_->GetQueryService().GetLaneIdsAtPosition(pose.position);
entity.SetAssignedLaneIds(lane_ids);
