Closing this bug as Invalid.
The real solution is fix-released in LP#1807023.
This bug was a workaround for not having ca-certificates in d-i and use an HTTP mirror that redirected to HTTPS
(the resulting certificate validation error couldn't be ignored due to HTTP protocol not using the wget option.)
But this is no longer required with the ca-certificates shipped in debian-installer.

Sorry, I had lost track of this bug.
