BREAKING CHANGE: `puppet.id` will change to `puppet.loggedInUserId`

## Before

1. `puppet.id` is defined as `undefined | string` and will be set when the puppet logged in with a user-id

## After

1. `puppet.id` will store a UUID when instantiating the Puppet, and the log on/off status will use `puppet.loggedInUserId` instead.
1. `currentUserId` will be defined as the `undefined | string` to store the logged in user id
