Add debug information to verify that we actually get the onDone event send to the driver page.

Rename to 'Sending events to driver page.'

(why did you call it 'onDone'?)

So this should have been isDone, I only do this if we have the isDone bool set

Sorry about that, please remove the 'if (isDone) {}'. 
I think it would be beneficial if we get this info every time we contact the
driving page (be it a status update or the final update)

So do something like this:

recordEvent('debug', 'Sending events to driver page (isFirstMessage = ' +
isFirstMessage + ', isStatusUpdate = ' + isStatusUpdate + ', isDone = ' + isDone
+ ')');

unconditionally

+    }
     // Post the DOM and all events that happened.
     var events = recordedEventList.slice(0);
     events.push(buildDomEvent());
