Dereference string* before printing it with "%s%".

Suggested by "go vet".
My mind is just blown that we have testing function which is returning a ```*string```. Yes, it'd be an extra few copies to return just a straight string but this is not a good time or place to be optimizing, and if we *really* wanted to optimize, we should be tossing around []byte, NOT *string.

So I would recommend scrolling up to the body function above and making it return something sane.
