Thanks for opening this PR @Raalsky! I dropped one copy request inline + adding @beckjake to review :)

This will trigger a warning on any project that doesn't have sources (that's what the tests are failing about). I think this is a good feature, but I think we're going to have to change a bit more about how node selection works for this to function.

I think we could change get_selected and select_nodes to handle this case a bit more carefully: instead of calling coalesce in get_selected, do the replacement in select_nodes and preserve the initial value. If it's None, skip the check.

This is most likely caused by a git client misconfiguration; please make sure to:

1. check if your git client is configured with an email to sign commits git config --list | grep email
2. If not, set it up using git config --global user.email email@example.com
3. Make sure that the git commit email is configured in your GitHub account settings, see https://github.com/settings/emails
