Lalit 59e78f96ba ts: Migrate people.js to TypeScript.
We use `get_by_user_id` instead of directly accessing the global dict, because
when accessing person objects directly from one of the global dicts we
need callers to check for undefined values, this can be fixed by using
`get_by_user_id` method to get person objects because that functions
makes sure to assert that we indeed have a valid user id, so it will
never return undefined values.
