Fix a few test failures when landing http://trac.webkit.org/changeset/57178.

      http://trac.webkit.org/changeset/57178 broke some tests in browser_test and ui_test.

This patch is same as the patch in http://codereview.chromium.org/3136019/show except test RedirectTest.ClientCancelled.

RedirectTest.ClientCancelled was broken on windows platform when landing the original patch. So I revert it.
After digging in code, I found the root cause of why the test was broken on windows platform. Please refer to 
http://crbug.com/53091 for details.
So I add FAILS_ prefix to RedirectTest.ClientCancelled on windows platform. 

BUG=17655
TEST=RedirectTest.ClientCancelled, AppApiTest.AppProcess, ExtensionBrowserTest.WindowOpenExtension, ExtensionBrowserTest.WindowOpenInvalidExtension
