bug#31892: guix pull ignores --substitute-urls in some cases

[Vagrant Cascadian]

I've seen this a few times, and it seems like guix pull remembers old
substitutes. I tried disabling one of the substitutes that guix-daemon
is configured to use since it wasn't online at the time, but it tries to
use it anyways:

guix pull --substitute-urls='http://10.0.0.15:8081 http://10.0.0.15:8082' 
--branch=elfutils-0.172 --url=/home/vagrant/src/guix-bare
