Original task statement excerpt

bug if column and param share the same name
### Version

1.30.0

### What happened?

A bug happened!
sql:
```
-- name: GetUserByEmail :one
SELECT email
FROM users
WHERE email = sqlc.arg(email);
```
generated:
```
func (q *Queries) GetUserByEmail(ctx context.Context, email string) (string, error) {
	row := q.db.QueryRow(ctx, getUserByEmail, email)
	err := row.Scan(&email)
	return email, err
}
```

on ErrNoRows, the function GetUserByEmail returns the input email... expected an empty string.
maybe create a separate string var like what is done with other types? after a little testing, this only happens when the names are the same xD
