Log Message

http/tests/eventloop/queue-task-across-cross-site-frames.html is flaky failure on iOS
https://bugs.webkit.org/show_bug.cgi?id=204510

Reviewed by Chris Dumez.

There are two issues with this test. First, queue-task-across-cross-site-frames.html wasn't waiting
for the helper file to post logs, and secondly, eventloop-helper.html was relying on setTimeout(~, 0)
to always happen after queued tasks had run, which is not always true if there had already been
another 0s timer scheduled.
