[BUG]: Single Selects don't work with JSON fields with bun:sqlite

### What version of `drizzle-orm` are you using?

0.29.3

### What version of `drizzle-kit` are you using?

0.20.12

### Describe the Bug

It seems like tables with a `text("name", { mode: "json" })` column can only be selected if more than one entry get's selected (e.g. `DB.query.Table.findMany().sync()` or `DB.select().from(Table).all()`)

### Expected behavior

If i use `.get()` or `.findFirst()` it gives me a error containing this
```m
291 | } else if (is(field, SQL)) {
292 | decoder = field.decoder;
293 | } else {
294 | decoder = field.sql.decoder;
295 | }
296 | result[selectionItem.tsKey] = value === null ? null : decoder.mapFromDriverValue(value);

SyntaxError: JSON Parse error: Unexpected identifier "undefined"

```

It looks like this originated from the utils.js file line 28 and relations.js line 296 (basically everytime it hits mapFromDriverValue)

This is because for example the code in utils.js
```js
const rawValue = row[columnIndex];
const value = node[pathChunk] = rawValue === null ? null : decoder.mapFromDriverValue(rawValue);
```
Results in rawValue being `undefined` because row is something like
```json
{
"count(*)": 8
}
```
Or any other object containing id and other key value columns and the code tries to index this object

I was able to temporary fix it by doing following:

utils.js
```js
const rawValue = row[columnIndex] || Object.values(row)[columnIndex];
const value = node[pathChunk] = rawValue === null ? null : decoder.mapFromDriverValue(rawValue);
```

relations.js
```js
const value = mapColumnValue(row[selectionItemIndex] || Object.values(row)[selectionItemIndex]);
const field = selectionItem.field;
let decoder;
if (is(field, Column)) {
decoder = field;
} else if (is(field, SQL)) {
decoder = field.decoder;
} else {
decoder = field.sql.decoder;
}
result[selectionItem.tsKey] = value === null ? null : decoder.mapFromDriverValue(value);
```

I basically saw that the code tried to index the values so i just converted the single objects to its values so it could get indexed properly

### Environment & setup

> Bun@1.0.23 (using bun:sqlite)
default setup with sqlite table using text with mode json and trying to select a single column
