Error: demo_user.js not auto-filling first name and last name

[alxiong]

there are a few issues/typo in gov-dmv/.../demo_user.js:

1. this line should be $('input[name="confirm_password"]').val(user_data.password ? user_data.password : "");, otherwise there will be console err saying cannot read unknown property of password -- user_data doesn't have a property called attributes, thus when accessing user_data.attributes.password, it would be an unknown property.
2. the default_attributes here needs to add two more fields -- first_name and last_name, otherwise those two fields won't be auto-filled. (based on the logic here)

thanks.
