Fixed Bug in Automatic Retries for DROP TABLE with ReplicatedMergeTree and Atomic Databases

Fixed a bug in automatic retries of DROP TABLE query with ReplicatedMergeTree tables and Atomic databases. In rare cases it could lead to Can't get data for node /zk_path/log_pointer and The specified key does not exist errors if the ZooKeeper session expired during DROP and a new replicated table with the same path in ZooKeeper was created in parallel. #46384 (Alexander Tokmakov).
