Currently, the engine asks the client to handle some type of requests externally.
But WebPageClient::handleStringPattern is not yet implemented and exposed to
the client. Before that, we still need to give the client a chance to decide
how to handle requests such as 'mailto:'.

To address this problem, r108763 introduced a change that ask the client to
decide how to handle the navigation in dispatchDecidePolicyForNewWindowAction().
This is not intuitive and will bring troubles, because this navigation will
happen in the new page. So the new page client is to decide how to handle
the navigation, not the old one.

This patch reverts r108763 and skips calling WebPageClient::handleStringPattern
since it's not implemented.

This way the new window action will continue, and the logic in
dispatchDecidePolicyForNavigationAction() will handle the navigation correctly.
