This ignore was here because `queryPartialDrvOutputMap` was used both 1. as a cache to avoid having to re-read the derivation (when gc-ing for example), and 2. as the source of truth for ca realisations The use-case 2. required it to be able to work even when the derivation wasn't there anymore (see https://github.com/NixOS/nix/issues/4138). However, this use-case is now handled by `queryRealisation`, meaning that we can safely error out if the derivation isn't there anymore
