json: method descriptors don't have "type" field

Getting this error:

Proto:

In "compiled" inline JS object:

export const PROTO_DEFINITIONS = {
  "nested": {

            },
            "SayHelloClientStream": {

          "fields": {
            "name": {
              "type": "string",
              "id": 1
            }
          }
        },
        "HelloReply": {
          "fields": {
            "message": {
              "type": "string",
              "id": 1
            }
          }
        }
      }
    }
  }
};

When I try to load it with fromJSON I get the error above. The error output has a bit of extra output I put in when debugging the issue. The "type" argument is undefined, probably because the methods do not have a "type" field on them from the pbjs output.

Fix: either put "rpc" in the type field in the pbjs output, or default "undefined" -> "rpc".
