What is the bug?

admitted_joins_do_not_disappear_after_a_merge wants a system resolv.conf and errors out otherwise.

This breaks the nix package builds, including the static binary build for the alpha.

Steps to reproduce

nix build https://forgejo.ellis.link/continuwuation/continuwuity

Server name and version

N/A, 93173313ea

Additional context

Mentioned in https://matrix.to/#/!c10y-8Hm3mAW99j9KEKoWPQH2M_FxGwG-EVHK06iLKg/$nyYKlU8FiupYYVlMiS1ZGeGheJtHtZ3JHqCNj039lfU?via=continuwuity.org&via=matrix.org&via=continuwuity.rocks.

TLDR for why this happens: When creating a DNS resolver, the code tries to read /etc/resolv.conf and fails early if it doesn't exist, even if you have set CONTINUWUITY_DNS_SERVERS.

Fix will be to only fail if both the file doesn't exist and the config parameter hasn't been set, and then setting the config param in the test.

Fix will be to only fail if both the file doesn't exist *and* the config parameter hasn't been set, and then setting the config param in the test.
