fixes bug 878109 - End Camino support in Socorro

WaterWolf was already used so doing a `s/Camino/WaterWolf` was not safe. 

The mess around WaterWolf is complex. The intention of using WaterWolf was to make sure we don't rely on any real data and that the code should work with any name. 

So what used to be Firefox, Camino, Thunderbird is now Firefox, SeaMonkey, Thunderbird. 
What it **should** throughout ALL tests is just WaterWolf and NightTrain. Right @rhelmer ?
