[Dirvish] Dirvish expiring newer images

[Loren M. Lang]

I have an old backup drive that I just put back into the rotation.  It
had some old images that are all now expired.  Since the vaults still
use the same configuration, I decided to just run dirvish-expire
followed by dirvish-runall and was surprised to see that dirvish-expire
expired all but the oldest good image.  I have no reason to believe that
at least some of the newer images had completed successfully.  It looks
like dirvish-expire does not expire images in the right order when all
images have expired.

# dirvish-expire; dirvish-runall
cannot expire server:default:20080423 No unexpired good images
server:default 20080424 2008-04-24 02:04  +28 days == 2008-05-22 02:03
server:default 20080425 2008-04-25 01:25  +28 days == 2008-05-23 01:24
