Fix timeout in update-and-send-events-replacment.html

The handling of iframe load events is finicky as indicated in the open
WHATWG issue:

https://github.com/whatwg/html/issues/490

This patch switches the wait mechanism to one that is well behaved
across browsers.  The new process arms the listener before inserting the
iframe into the document.
