**Describe the bug**
columns('regexp') didn't return all columns by regexp where 3+ joins in query 

**Does it reproduce on recent release?**
version 21.3.4 revision 54447

**How to reproduce**

in query we have 3 columns 'test' but returned only one:

```
select columns('test') from                                                                                                                                                               
(select 1 as id, 'a' as test) a                                                                                                                                                                    
left join (select 1 as id, 'b' as test) b on b.id = a.id                                                                                                                                               
left join (select 1 as id, 'c' as test) c on c.id = a.id;

1 rows in set. Elapsed: 0.007 sec.
```

but if we change query:

```
select  columns('test'), a.test as t1, b.test as t2, c.test as t3 from 
(select 1 as id, 'a' as test) a 
left join (select 1 as id, 'b' as test) b on b.id = a.id 
left join (select 1 as id, 'c' as test) c on c.id = a.id
