We were not waiting for a publisher to catch up with the subscriber after creating a subscription. Now, it can happen that apply worker starts replication even after we have disabled the subscription in the test. This will make the test expect that there is no active slot whereas there exists one. Fix this symptom by allowing the publisher to wait for catching up with the subscription. It is not a good idea to ensure if the slot is still active by checking for walsender existence as we release the slot after we clean up the walsender related memory. Fix that by checking the slot status in pg_replication_slots. Also, it is better to avoid repeated enabling/disabling of the subscription. Finally, we make autovacuum off for this test to avoid any empty transaction appearing in the test while consuming changes.
