apt-smart seems to fail when a mirror redirects

[nergdron]

Been noticing lately that some of the fastest mirrors here in western canada fail to get properly evaluated by apt-smart because they redirect to a different domain:

$ apt-smart -l

layeronline specifically redirects to https://mirrors.edge.kernel.org/ubuntu/, which is the fastest mirror from my ISP, but apt-smart ignores it. would be great if apt-smart was able to follow redirects and still eval these mirrors.
