settings_users: Use user_ids for the users list_render.

This is part of a refactor that aimed to remove /json/users calls,
as we can get all the information needed on people API.

Now, the list render for $users_table and $deactivated_users_table
uses user_ids instead of user objects, as the people API give us
a filtered list of active_user_ids and non_active_user_ids.
