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.
