SPARK-1577: Enabling reference tracking by default in GraphX
KryoRegistrator.
We had originally disabled reference tracking by default however this now
seems to create serious issues in the spark-shell where even the following
benign block of code will fail:
```scala
class A(a: String) extends Serializable
val x = sc.parallelize(Array.fill(10)(new A("hello")))
x.collect
```
