OPC UA: Empty href with base is not accepted

[egekorkan]

The following TD is not accepted due to href being empty:

{
      "@context": [
          "https://www.w3.org/2022/wot/td/v1.1"
      ],
      "base": "opc.tcp://localhost:4840",
      "properties": {
          "test123": {
              "forms": [
                  {
                      href: "", // this is the issue
                      "op": [
                          "readproperty",
                          "writeproperty",
                          "observeproperty"
                      ],
                      "opcua:nodeId": "ns=3;s=\"foobar\""
                  }
              ],
              "observable": true,
              "readOnly": false,
              "type": "number"
          }
      },

After #1368 this should be no issue anymore, right?
