[MC-12370] TNT minecarts do not damage rails when exploding.

I was playing on creative to test out all the new features of the 1.5 update and started messing around with the TNT carts.
After building my railway i noticed the TNT carts do not damage the rails.
I dont know if this is a bug or on purpose to save rails but i think its a problem.

This isn't a bug, this is something that Jeb fixed. Or else you would have to build your rails again and again.
