Deflake xss-DENIED-to-javascript-url-in-foreign-domain-subframe.html

This test was flaky because the iframe sent a postMessage to the parent
frame in its load handler. However, the parent frame may or may not have
run its load handler. If the parent frame's load handler hadn't run yet,
then there would be no handler for a postMessage. To prevent this race,
don't load the iframe until the parent frame is fully initialized.
