Bot confuses Northern Ireland with Ireland

[chirlu]

Just stumbled over this edit (old, but the relevant code apparently hasn’t changed since): http://musicbrainz.org/edit/16123544
Here, the country was set as “Ireland” based on the Wikipedia category “Irish alternative rock groups”. However, the Wikipedia article (http://en.wikipedia.org/wiki/Window_Seats) clearly states the band is from Northern Ireland, i.e. from the UK.
