news: simplify isRelevant() check

Hopefully a bit easier to follow now. I'm also not convinced
it was right before, as the previous required every restriction.checkRestriction(...)
to be true, while the original code only required *one* to be true per
restriction.

Thanks to kurly for noticing a recent news item wasn't showing up.
