I am using `nullIf` in aggregations to skip unwanted empty strings. Strangely enough `any` function picks `NULL`s resulting from `nullIf`, i.e. does skip them as it should do with NULLs.

### Minimal reproducing code
```sql
select any(nullIf('', ''), 'some text');
```
produces:
```
┌─nullIf('', '')─┐
│ ᴺᵁᴸᴸ           │
└────────────────┘
```

**Expected behavior**
This should return 'Some text'

### Other example with table
```sql
create temporary table vv (m Nullable(String));
insert into vv (*) values (''), ('Some text');
select any(nullIf(m, '')) from vv;
```
result:
```
┌─nullIf(any(m), '')─┐
│ ᴺᵁᴸᴸ               │
└────────────────────┘
```
expecting 'Some text' as before
