# Description
This PR directly removes test accounts, and not just flag them, from:
* `int_core__unified_user`, which means is also propagated to `int_core__user_host`.
It does so by creating a new, extremely simple model named: `int_core__user_test_account`
Then, `int_core__user_host` is inner joined with a small explanation comment on:
* `int_core__accommodation`
* `int_core__unique_accommodation_to_user`
* `int_core__bookings`
* `int_core__verification_requests`
* `int_core__payments`
Effectively removing test accounts.
Lastly, any existence and usage of the column `is_test_account` has been removed -> mostly on New Dash-related models.
