[patch] unicode problem with DJabberd::RosterStorage::SQLite

A perl program has to use Perl's UTF8 scalars everywhere, or nowhere,
otherwise introducing them (as this patch does) starts the contagious
spread of them... whenever one touches a non-UTF8 scalar, perl starts
converting the one that's touched.

I imagine we do use it, though, as XML libraries tend to use it?

So this _should_ be safe and the correct fix (I've seen the same bug,
btw), but I want somebody to double-check we are using Perl's UTF-8 for

Can somebody look at Devel::Peek on a scalar (say a username) when a
non-ASCII username comes in, and see if the SvUTF8 flag is on?
