Fail to find artifact for core modules pinned in the snapshot

[miyagawa]

When the snapshot contains core modules lower than the core version, Carmel will complain that it can't find the artifact for it.

This could happen when you migrate the snapshot from Carton, or upgrade perl versions.

➜  cat cpanfile          
requires 'HTTP::Tinyish';

➜  grep HTTP-Tiny- cpanfile.snapshot      
  HTTP-Tiny-0.070                                           
    pathname: D/DA/DAGOLDEN/HTTP-Tiny-0.070.tar.gz

➜  corelist -a HTTP::Tiny | grep 5.32
  v5.32.0    0.076         
  v5.32.1    0.076     

➜  carmel
Using HTTP::Tinyish (0.14)

Can't find an artifact for HTTP::Tiny => 0.055
You need to run `carmel install` first to get the modules installed and artifacts built.

The problem persists until you delete cpanfile.snapshot to start over.
