Assume the container is removed if it is not show in docker ps
Assume the container is removed if it is not show in docker ps

In some case, docker can not remove container and raise following error
message:

    Unable to remove filesystem for xxx remove
    /var/lib/docker/containers/xxx/shm: device or resource busy

But the container is removed. This patch assumes container is
removed if only container name is not shown in docker ps.
