By hooking into `terms_pre_query` after the fixture posts and terms are created but before the actual taxonomy query runs, we ensure that the correct SQL query from `WP_Term_Query::get_terms()` is tested for requested term limits, rather than the one initiated from `wp_insert_post()` or `wp_insert_term()` via `term_exists()`.
