[BlackBerry] Basic authentication challenge credentials for stored credentials again after restarting browser
https://bugs.webkit.org/show_bug.cgi?id=96362

Patch by Sean Wang <Xuewen.Wang@torchmobile.com.cn> on 2012-09-19

Source/WebCore:

This patch enable reading credentials from the persistent credential storage
when it is not private browsing mode and there is not a credential in the RAM
for the requested resource.

Since we don't load persistent stored credentials into RAM at the starting time,
even we have saved the credentials at the last browsing, after restarting the browser,
it will still challenge for credentials for the requesting resources.

No new tests, it uses the original authentication tests. There is no way to
clear all credentials or restarting browsers to test this feature.
