[WK2 NetworkProcess] Cannot log into gmail/facebook with private browsing enabled

[Alexey Proskuryakov]

Cannot log into gmail/facebook with private browsing enabled.

A wrong storage session is used after a redirect. This is because ResourceHandle::willSendRequest() first sets storage session, and then calls the client. NetworkProcess client in particular doesn't preserve the storage session, because it cannot be serialized for IPC.

I don't think that the client should be able to change storage session, even for WebKit1, where NSURLRequest is part of API.

It looks like this causes 12 test cases on Win7 to crash:
