I found that certain docker installations do not handle binding to the source directory quite right. Just writing it based on help from backjlack and tibor in IRC.

Fix: Failed Start breaks VolumesFrom

Running parseVolumesFromSpec on all VolumesFrom specs before initialize
any mounts endures that we don't leave container.Volumes in an
inconsistent (partially initialized) if one of out mount groups is not
available (e.g. the container we're trying to mount from does not
exist).

Keeping container.Volumes in a consistent state ensures that next time
we Start() the container, it'll run prepareVolumes() again.

The attached test demonstrates that when a container fails to start due
to a missing container specified in VolumesFrom, it "remembers" a Volume
that worked.
