What is broken is that volumes that came into cinder via manage, and
volumes that came into cinder via volume create behave differently
when unmanaged.

Since manage and unmanage would generally be run with a  very long
separation in time, there is no reason for the admin to expect some
volumes to be renames and some not when they do the unmanage.
