**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.
{
    DataPartsVector total_covered_parts;
    if (!isEmpty())
    {
        auto parts_lock = acquired_parts_lock ? MergeTreeData::DataPartsLock() : data.lockParts();
        auto * owing_parts_lock = acquired_parts_lock ? acquired_parts_lock : &parts_lock;
        auto current_time = time(nullptr);
        size_t add_bytes = 0;
        size_t add_rows = 0;
        size_t add_parts = 0;
        size_t reduce_bytes = 0;
        size_t reduce_rows = 0;
        size_t reduce_parts = 0;
        for (const DataPartPtr & part : precommitted_parts)
        {
            DataPartPtr covering_part;
            DataPartsVector covered_parts = data.getActivePartsToReplace(part->info, part->name, covering_part, *owing_parts_lock);
            if (covering_part)
            {
