Reviewed by Ojan Vafai.

The tests were racing the load time of js-test-post.js and the test completion.
Previously, js-test-post.js would already be in the cache, so it would always load first.
Now that we clear the cache, sometimes js-test-post.js would run after the other test output.
Fix this by setting window.jsTestIsAsync = true and calling finishJSTest() when the test
ends (this delays the js-test-post.js output until finishJSTest() is called).
