[k-morozov]

Test that reproduce problem was added.

    When we execute query on clickhouse02                         # tests/integration/steps/clickhouse.py:106 0.006s
      """
      SELECT id, visits FROM test_db.hits FINAL ORDER BY id FORMAT Vertical;
      """
    Then we get response                                          # tests/integration/steps/clickhouse.py:132 0.000s
      """
      Row 1:
      ──────
      id:     1
      visits: 106
      """
      Assertion Failed: 
      Expected: 'Row 1:\n──────\nid:     1\nvisits: 106'
           but: was 'Row 1:\n──────\nid:     1\nvisits: 105'
