bug#38997: guix import: error: make-session: unbound variable

[Sergiu Marton]

It seems that guix import gives me:

guix/build/download.scm:248:2: In procedure tls-wrap:
error: make-session: unbound variable

for every importer that need to download something from the internet.

Here's the full output when trying to import persistent-postgresql
(https://hackage.haskell.org/package/persistent-postgresql).
