fix import of editions without isbn or external id

[maxlath]

This is done by generalizing the use of the resolver to create entities from edition+works+authors seeds, which would be made possible by https://github.com/inventaire/inventaire/pull/636

This would solve the issue of edition seeds without isbn and without other edition identifiers, such as is the case with LibraryThings entries, which have a work id but no edition id. Example with this export sample, which currently generates an error but would work after this PR:
