### Describe the bug and provide the minimal reproduce step

window assigns in group by is different in same logic
### execute insert sql
`insert into root.hess.test.AK1407120700022.testdata (timestamp, epv_total, eload_total) VALUES (2592000000,1,1),(5011199999,2,2),(5011200000,3,3),(7689599999,4,4),(7689600000,5,5)`
`insert into root.hess.test.AK1407120700022.testdata (timestamp, epv_total, eload_total) VALUES (2563200000,10,10),(4982399999,20,20),(4982400000,30,30),(7660799999,40,40),(7660800000,50,50)`
### then execute query sql
`select SUM(epv_total) as pv,SUM(eload_total) as load from root.hess.**.AK1407120700022.** group by ([1970-02-28T08:00:00, 1970-05-31), 1mo , 2mo)`
`select SUM(epv_total) as pv,SUM(eload_total) as load from root.hess.**.AK1407120700022.** group by ([1970-02-28T08:00:00, 1970-05-31), 1mo , 1mo)`

### What did you expect to see?

IoTDB> select SUM(epv_total) as pv,SUM(eload_total) as load from root.hess.**.AK1407120700022.** group by ([1970-02-28T08:00:00, 1970-05-31), 1mo , 2mo)

Chạy hai truy vấn GROUP BY được cung cấp trên IoTDB 1.1.1 sau khi chèn các hàng đã liệt kê, rồi so sánh các kết quả 1mo, 2mo và 1mo, 1mo. Truy vết hành vi gán cửa sổ trong query engine; hoàn thành khi logic cửa sổ tương đương tạo ra các phép gán khoảng nhất quán và các truy vấn tái hiện trả về các hàng mong đợi.
