Fix WebViewTest.CloseOnLoadcommit flakiness.

Fix WebViewTest.CloseOnLoadcommit flakiness.

The test used to synchronously issue chrome.test.sendMessage from
chrome.app.window.create's creation callback. Since the app window
also loads a frame, this exposes a race, described in
http://crbug.com/620194.

Let the sendMessage happen in a setTimeout so the race is worked
around.
