pgstat: fix subscription stats entry leak. Commit 7b64e4b3 taught DropSubscription() to drop stats entry of subscription that is not associated with a replication slot for apply worker at DROP SUBSCRIPTION but missed covering the case where the subscription is not associated with replication slots for both apply worker and tablesync worker. Also add a test to verify that the stats for slot-less subscription is removed at DROP SUBSCRIPTION time. Backpatch down to 15.
