**Describe the unexpected behaviour**

Not sure if it is a bug but we encounter a very strange issue when using the same field 2 times in a where clause.
Basically : field = <> and toYear(field)= <>

**How to reproduce**
* Clickhouse 20.5.2.7


Create table statement :
```
DROP TABLE IF EXISTS datasources.cal_pace_strange2;
CREATE TABLE datasources.cal_pace_strange2
(
    `htl_id` UInt32,
    `stay_date` Date,
    `snpdate` Date,
    `leadtime` String,
    `los` String,
    `mkt_id` String,
    `sob_id` String,
    `res_status_id` String,
    `rt_id` String,
    `cur` String,
    `rns` Decimal(9, 4),
    `arrivals` Decimal(9, 4),
    `departures` Decimal(9, 4),
    `adults` Decimal(9, 4),
    `children` Decimal(9, 4),
    `rm_rev` Decimal(18, 10),
    `fd_rev` Decimal(18, 10),
    `oth_rev` Decimal(18, 10),
    `tot_rev` Decimal(18, 10)

)
    ENGINE = MergeTree()
        PARTITION BY toYYYYMM(snpdate)
        ORDER BY (htl_id, stay_date, snpdate)
        SETTINGS index_granularity = 8192;
```

Load the data using the attached SQL inserts.

This query returns 0 results :

`select * from cal_pace_strange2 where snpdate='2020-06-09' and htl_id=66 and stay_date='2020-10-02' and toYear(stay_date) = 2020;`

This one return the correct results :

`select * from cal_pace_strange2 where snpdate='2020-06-09' and htl_id=66 and stay_date='2020-10-02'`

Same behavior occurs in 20.4.3 and 20.4.4

Expected behavior :

Both queries should return the same results.
