I have now implemented this method and added extractPublicKey() to the private key in this pull request: https://github.com/openpgpjs/openpgpjs/pull/53
For private keys exported with GPG or generated with OpenPGP.js this extracts a valid public key. Private keys exported with PGP do not contain any signatures, therefore it's not possible to create a public key and null is returned.
