Subject: bug#38798: `guix pull --list-generations` fails ungracefully when it cannot find the path a repo URI used in a guix generation

I get 'guix pull: error: Git error: failed to resolve path' during the output and then it stops. It should just ignore the news output for that entry and carry on.
