When trying to populate a newly created GraphiteMergeTree table with some data, I catch an exception.

```sql
CREATE TABLE default.ttt
(
    `C1` Int8,
    `Sign` Int8,
    `Version` UInt8,
    `Path` String,
    `Time` DateTime,
    `Value` Int8
)
ENGINE = GraphiteMergeTree('graphite_rollup_params')
ORDER BY tuple()
```
Table is created and it shows up in `SHOW TABLES`. Then, I try to insert some data:

```sql
tietokone :) INSERT INTO ttt (*) VALUES (1, 1, 2, 'qwew', '2021-12-12 01:01:02', 2)

INSERT INTO ttt (*) VALUES

Received exception from server (version 21.9.4):
Code: 49. DB::Exception: Received from localhost:9000. DB::Exception: Invalid number of rows in Chunk column Int8 position 5: expected 1, got 8. (LOGICAL_ERROR)
```

This happens on `21.3`, `21.8`, `21.9`
However, `20.3`, `20.8` work as expected
