`DOLT_LOG` behaves incorrectly when used in a lateral join.

### Query

```sql
select l.commit_order as child, r.commit_order as parent from dolt_log() l join lateral (select * from dolt_log(l.commit_hash)) r;
```

### Expected behavior

For each commit, we expect a row for each of that commits parents.

So if there are four commits on the branch, we would expect to see this result:

```
+-------+--------+
| child | parent |
+-------+--------+
| 4 | 4 |
| 4 | 3 |
| 4 | 2 |
| 4 | 1 |
| 3 | 3 |
| 3 | 2 |
| 3 | 1 |
| 2 | 2 |
| 2 | 1 |
| 1 | 1 |
+-------+--------+
```

### Actual behavior

Instead, we get an error: `unable to find field with index 1 in row of 0 columns`

e5951800a4204fadf524b1e4231d08d12d636657 fixes this, but now we get the following incorrect results:

```
+-------+--------+
| child | parent |
+-------+--------+
| 4 | 4 |
| 4 | 3 |
| 4 | 2 |
| 4 | 1 |
| 3 | 4 |
| 3 | 3 |
| 3 | 2 |
| 3 | 1 |
| 2 | 4 |
| 2 | 3 |
| 2 | 2 |
| 2 | 1 |
| 1 | 4 |
| 1 | 3 |
| 1 | 2 |
| 1 | 1 |
+-------+--------+
```

It seems like the arguments to DOLT_LOG are being ignored if they aren't constant.
