tests: fix 00705_drop_create_merge_tree flakiness CI caught tiemout for this test [1]: 2022.10.19 16:43:46.238264 [ 24048 ] {aea0ff2a-f8de-498a-bd9f-0b8069a49f48} <Error> executeQuery: Code: 60. DB::Exception: Table test_orfkwn0y.table doesn't exist. (UNKNOWN_TABLE) (version 22.10.1.1) (from [::1]:60028) (comment: 00705_drop_create_merge_tree.sh) (in query: DROP TABLE table), Stack trace (when copying this message, always include the lines below): ... 2022.10.19 16:53:34.484777 [ 24042 ] {aec5a80a-4492-429b-87fb-7dbf5ffb5d67} <Debug> executeQuery: (from [::1]:57944) (comment: 00705_drop_create_merge_tree.sh) DROP DATABASE test_orfkwn0y (stage: Complete) But as you can see there is huge delay between last query from the test and final DROP DATABASE.

[1]: https://gist.github.com/azat/affbda3f8c6b5c38648d4ab105777d88 Anyway it is easier to simply invoke clickhouse-client only two times, since each invocation is very slow (~1-2 sec) in debug build.
