Product purchase records being deleted incorrectly

in moneysuite/ms_core/ms_products/ms_products.module line 401 is function ms_products_user_cancel which does:

/**
 * Implements hook_user_cancel().
 */
function ms_products_user_cancel($edit, $account, $method) {
  // Delete all purchases related to a user when the user is deleted.
  $result = db_delete('ms_products_purchases')
    ->condition('uid', $account->uid)
    ->execute();
  return $result;
}

When I canceled two user accounts and chose "Disable the account and keep its content. ", I saw that the records were deleted from ms_products_purchases.

It seems that function hook_user_delete is the correct choice for the deletion of ms_products_purchases.

I will provide a patch shortly.
