Bug 1683244 - Part 1: Fix the issue that `save As` of multiple selected links in PageInfo media tab doesn't work. r=smaug

The root cause is that it doesn't pass the cookieJarSettings parameter
when calling the internalSave() in pageInfo.js. This patch fixes this by
passing the correct cookieJarSettings which was passed via the
'PageInfo:getData' message.
