Frontpage failure for javascript popups

Fixed failure when fetching frontpage 'nyt fra' so that we only fetch VisNytFra messages.

This prevented an error for a frontpage with 'Driftsstatus'(opened in javascript window). This fix simply ignores messages like that so that we don't fail


Please merge this so that I can run the full script with the "DRIFTSSTATUS" on the frontpage in 'nyt fra' section
