FrameLoaderClient::assignIdentifierToInitialRequest() not called for the main resource when loaded from the memory cache

When the main resource is loaded from the memory cache the
response is not added to the ResponseVector of the document
loader, so that when committing the provisional load the remaining
delegate messages are not called because the ResponseVector of the
document loader is empty. When the main resource is loaded from
the memory cache, there's no resource loader, and the client is
notified about the response received using
ResourceLoadNotifier::dispatchDidReceiveResponse() directly
instead of ResourceLoadNotifier::didReceiveResponse() which is the
one adding the response to the ResponseVector of the document
loader. So, the problem can be fixed by adding the response to the
ResponseVector before calling dispatchDidReceiveResponse() when
loading the main resource without a resource loade
