dockerclean removes images in use

[daniel86]

Calling dockerclean yields a state where images used by some containers are removed and containers can not start anymore. For example:

$ ./scripts/start-apt-cacher 
apt-cacher container exists, starting it...
Error response from daemon: get 2ca745e397eb6f091b40dcef8b07da7582d38d90f01d1946c9d1f53e0b75a47d: volume not found
Error: failed to start containers: apt-cacher-run
Failed to start apt-cacher container.

Removing foobar'd containers manually, then rebuilding fixes it. For example:

$ doocker rm apt-cacher-run

docker version: 1.13.1
