Upgrading multiseries Charm

[Rick Harding]

Oops sorry. It's what I get for replying while out. So the series in
metadata.yaml is ordered by preferred series. However, you're completely
correct that upgrade should not be attempting to upgrade across series with
an upgrade charm. We'll look into this and file a bug as soon as we
replicate.
