Bug#311092: negative unread messages number

[Andrew Schulman <andrex@alumni.utexas.net>]

> I'm not sure why but I see negative number of unread messages after 
> I've fetched newsgroups articles.
> After restarting Kontact the number is calculated correctly.
> This may be related to the fact that I have set a few newsgroup
> discussions to "ignore".
