**How to reproduce**
Clickhouse server 20.13.1.5273
```
CREATE TABLE default.test
(
`key` UInt32,
`ts` DateTime CODEC(DoubleDelta, LZ4),
`db_time` DateTime DEFAULT now() COMMENT 'spout-ignore' CODEC(DoubleDelta, LZ4)
)
ENGINE = MergeTree
PARTITION BY toStartOfTenMinutes(db_time)
ORDER BY (key, ts)
TTL db_time + toIntervalHour(3)
SETTINGS index_granularity = 8192, merge_with_ttl_timeout = 3600, min_rows_for_compact_part = 1000000, min_bytes_for_compact_part = 200000000, in_memory_parts_enable_wal = 0;


INSERT INTO test(key, ts) SELECT number % 1000, now() + intDiv(number,1000) FROM numbers(500);

SELECT * FROM test;
500 rows in set. Elapsed: 0.003 sec.

DETACH TABLE test;

ATTACH TABLE test;

SELECT * FROM test;

0 rows in set. Elapsed: 0.002 sec.
```

**Expected behavior**
Clickhouse would flush parts on disk.
if (!matcher(partition_id))
                continue;
            const auto & path = it->path();
            disk->removeRecursive(path);
            result.push_back(PartitionCommandResultInfo{
                .partition_id = partition_id,
                .part_name = partition_directory,
                .backup_path = disk->getPath() + backup_path.generic_string(),
                .part_backup_path = disk->getPath() + path,
                .backup_name = backup_name,
            });
            LOG_DEBUG(log, "Unfreezed part by path {}", disk->getPath() + path);
        }
    }
    LOG_DEBUG(log, "Unfreezed {} parts", result.size());
    return result;
