[v2 Bug] Preview CTE failure on CTE containing Jinja whitespace control

### Is this a new bug in dbt v2.x compared to the latest version of dbt 1.x?

- [x] I believe this is a new bug in dbt v2.x

### Current Behavior

"Preview CTE" fails when attempting to preview CTE containing Jinja whitespace control. `dbt show` / `dbt show --inline` on the full model SQL succeeds.

### Expected Behavior

Preview CTE works on CTEs containing Jinja whitespace control.

### Steps To Reproduce

1. Create a model:
```sql
-- model.sql
WITH cte AS (
SELECT
{{- " 1 " -}} AS foo
)

SELECT *
FROM cte
```
2. Click "Preview CTE" and observe error:
```

```

### Relevant log output
