clientCertificate should be string instead of list

[makagonr]

Environment

ACC 1.12

Summary

According to AS3 schema, inside "TLS_Client" class, field "clientCertificate" should be string, but 1.12 ACC produces a list of strings.

                "custom_ssl_server_profile": {
                    "clientCertificate": [
                        "custom_ssl_cert_key"
                    ],  
                    "ciphers": "DEFAULT",
                    "class": "TLS_Client"
                },  
...
