API exercise jwt payload should be a plain object

[samuelchvez]

Found that jwt library expects the payload to be a plain object. As seen in the course, we send directly the sequelize model instance, which is not a plain object. To solve it, I used the method short() inside the generateJWT method:

function generateJWT(user: User): string {
    return jwt.sign(user.short(), config.jwt.secret);
}
