**Describe what's wrong**

Including a LowCardinality column in an `ON` clause containing an `OR` operator results in this exception:

```
DB::Exception: Expected ColumnLowCardinality, got String: While executing JoiningTransform. (ILLEGAL_COLUMN)
```

**Does it reproduce on recent release?**

22.1.2

**How to reproduce**

Minimal repro case:

```sql
WITH t1 AS
    (
        SELECT toLowCardinality('x') AS col
    )
SELECT *
FROM t1
INNER JOIN t1 AS t2 ON (t1.col = t2.col) OR (t1.col = t2.col)
```

However, casting to String works:

```sql
WITH t1 AS
    (
        SELECT toLowCardinality('x') AS col
    )
SELECT *
FROM t1
INNER JOIN t1 AS t2 ON (CAST(t1.col AS String) = CAST(t2.col AS String)) OR (CAST(t1.col AS String) = CAST(t2.col AS String))
```

Without `OR`, casting is not necessary:

```sql
WITH t1 AS
    (
        SELECT toLowCardinality('x') AS col
    )
SELECT *
FROM t1
INNER JOIN t1 AS t2 ON t1.col = t2.col
```

**Expected behavior**

It should not be necessary to use CAST when joining on a LowCardinality column with multiple `OR` expressions.

        assert(table_join.getDictionaryReader());
        table_join.getDictionaryReader()->readKeys(*key_columns[0], read_result, found, positions);
