New regression: FranceTVInfoIE

[anisse]

Since 99892e9 , there's a new test failing in francetvinfo ie. It's not a big issue, just the description that needs to be updated. Previously the description was fetched in dailymotion's description, now it's from the webpage meta description tags. Here they differ, and I don't know which one is better.
