Rather than comb through the charm updating all the call sites, I've
made a hack to ensure config values never get returned as null. I also
didn't want to change the style, as the alternative (using
config.get()) can hide other bugs.

Other charms will have the same problem, so this should certainly be
fixed in Juju.
