If name of key column equals in both tables in Storage Join `JOIN ON` trows an error:

```
:) CREATE TABLE t1 (x String) ENGINE = TinyLog;

:) CREATE TABLE t2 (x String) ENGINE = Join(ALL, INNER, x);

:) select * from t1 join t2 USING(x);

Ok.

0 rows in set. Elapsed: 0.036 sec.

:) select * from t1 join t2 ON (t1.x == t2.x);

0 rows in set. Elapsed: 0.026 sec.

Received exception from server (version 21.3.1):
Code: 8. DB::Exception: Received from localhost:9000. DB::Exception: Cannot find column `t2.x` in source stream.

```

If secondary column name match we tables cannot be joined with `USING` too:

```
:) CREATE TABLE t1 (x String, y String) ENGINE = TinyLog;

:) CREATE TABLE t2 (x String, y String) ENGINE = Join(ALL, INNER, x);

:) select * from t1 join t2 USING(x);


0 rows in set. Elapsed: 0.027 sec.

Received exception from server (version 21.3.1):
Code: 8. DB::Exception: Received from localhost:9000. DB::Exception: Cannot find column `t2.y` in source stream.
