In this case, there's no protocol version that we can extract for
nsIHttpChannel.
The code that does the redirect is here: 7f3d9fce41/docshell/base/nsDocShell.cpp (L6079-L6095)

infrastructure for this kind of tests (but it'll be cool to have it).

Note: this will have 2 screencast tests failing. Investigation is in a follow-up.
