Implement messageerror event:
- https://github.com/whatwg/html/pull/2530

Previously, WebKit would fire a `message` event with its `data` being null,
whenever data deserialization would fail. This wasn't as per specification and
did not match other browser engines. We're supposed to fire a `messageerror`
event instead.

This patch addresses the issue.
