What makes a spark plug do this?

Just got my bike back from a shop, had my top end ported and rebuilt. The guy tells me to get it broke in(2 tanks easy riding up and down through the gears) then bring it back in to be dyno'ed and tuned. I make it to a tank and 1/2 and my plug backs out and looks like this. When you have a shop do this kind of work, is it safe to assume that they would put new plugs in? Sorry my pic file is too big or something but it is dark grey almost black, the electrode is gone and the prong is broken or burned up. I think it broke somehow and ended up in my bottom end because now my left side is knocking and smoke and heat only coming out of right side. Not sure if I'm being unreasonable but it seems to me if you take a bike in that isn't running, they tell you what you need and you do it, then something like this shouldn't have happened.
