The openssh-server.postint does have code to create missing host keys:

host_keys_required() {
        hostkeys="$(get_config_option HostKey)"
        if [ "$hostkeys" ]; then
                echo "$hostkeys"
        else
                # No HostKey directives at all, so the server picks some
                # defaults depending on the setting of Protocol.
                protocol="$(get_config_option Protocol)"
                [ "$protocol" ] || protocol=1,2
                if echo "$protocol" | grep 1 >/dev/null; then
                        echo /etc/ssh/ssh_host_key
                fi
                if echo "$protocol" | grep 2 >/dev/null; then
                        echo /etc/ssh/ssh_host_rsa_key
                        echo /etc/ssh/ssh_host_dsa_key
                        echo /etc/ssh/ssh_host_ecdsa_key
                        echo /etc/ssh/ssh_host_ed25519_key
                fi
        fi
}

And running "dpkg-reconfigure openssh-server" fixes the issue.
