Handle null CFArrayRef returning from _CFHTTPParsedCookiesWithResponseHeaderFields

Per CF API naming conventions, this SPI is allowed to return null, and it sometimes does.

Properly handle he null check so our "createCookies" function never returns null.

Peculiar that this one function returns CFArrayRef rather than RetainPtr<CFArrayRef>, when all the rest in the file use RetainPtr. I think we should come back here and change it.

Too bad there is no CF equivalent to @[], annoying to create a new array every time, although not a real problem.

CookieJarCFNet.cpp is no more in same shape or form but we still have following:

https://github.com/WebKit/WebKit/blob/a2db53cd97dc8136ac5c2a22d4cd2b53d0d717d6/Source/WebCore/platform/network/cf/NetworkStorageSessionCFNetWin.cpp#L228


and this ASSERT already added:

Do we need anything from this patch or we can close this? Thanks!
