Typescript generated client uses inconsistent casing for property names

See original GitHub issue

For this definition in JSON I have Username and Password properties.

"definitions": {
    "TokenRequest": {
      "type": "object",
      "additionalProperties": false,
      "properties": {
        "Username": {
          "type": "string"
        },
        "Password": {
          "type": "string"
        }
      }
    },

The angular client I’m generating contains the following interface for an ITokenRequest and (as expected) makes the properties lowercase to conform to JS conventions.

export interface ITokenRequest {
    username?: string | undefined;
    password?: string | undefined;
}

However the init() function does not change the casing and gives me this.username = data["Username"]; and you end up with undefined for all the properties.

export class TokenRequest implements ITokenRequest {
    username?: string | undefined;
    password?: string | undefined;

    constructor(data?: ITokenRequest) {
        if (data) {
            for (var property in data) {
                if (data.hasOwnProperty(property))
                    (<any>this)[property] = (<any>data)[property];
            }
        }
    }

    init(data?: any) {
        if (data) {
            this.username = data["Username"];
            this.password = data["Password"];
        }
    }

    static fromJS(data: any): TokenRequest {
        data = typeof data === 'object' ? data : {};
        let result = new TokenRequest();
        result.init(data);
        return result;
    }

    toJSON(data?: any) {
        data = typeof data === 'object' ? data : {};
        data["Username"] = this.username;
        data["Password"] = this.password;
        return data; 
    }
}

This is with all the latest bits from today using msbuild targets to generate the code. I haven’t used nswag in a couple months, so can’t say exactly when this started.
