**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.
PartLogElement::Type type,
    const ExecutionStatus & execution_status,
    UInt64 elapsed_ns,
    const String & new_part_name,
    const DataPartPtr & result_part,
    const DataPartsVector & source_parts,
    const MergeListEntry * merge_entry)
try
{
    auto table_id = getStorageID();
    auto part_log = getContext()->getPartLog(table_id.database_name);
    if (!part_log)
        return;
    PartLogElement part_log_elem;
    part_log_elem.event_type = type;
    part_log_elem.error = static_cast<UInt16>(execution_status.code);
    part_log_elem.exception = execution_status.message;
    /
    /
    const auto time_now = std::chrono::system_clock::now();
    part_log_elem.event_time = time_in_seconds(time_now);
    part_log_elem.event_time_microseconds = time_in_microseconds(time_now);
