Calling a method on null should throw a NullPointerException

[OlivierBlanvillain]

At this point it throw a ☹ TypeError. Here is a failing test:

it("should throw a NullPointerException when calling a method on null") {
  try {
    null.toString()
  } catch {
    case e: NullPointerException => ()
  }
}

Hi @OlivierBlanvillain !
This is an intended semantic difference as documented here:
http://www.scala-js.org/doc/semantics.html#exceptions
Well, not exactly intended, but something I don't plan to "fix". Throwing proper NullPointerExceptions would require lots of additional runtime checks, for an exception which is not supposed to be thrown in a bug-free program anyway.

It is very refreshing to read this.
