[PATCH] PublicInbox::Inbox.pm: Default unset address to a one element array

[ebiederm@xmission.com (Eric W. Biederman)]

PublicInbox::Config.pm::_fill() assumes that address is an array.
Therefore when handling an unset address use an array containing a
single string, instead of a single string.

I accidentially created a public inbox without an address at some
point and had some nasty errors because the default value
we game to address is not an array.
