finally block getting called twice?
In my terminal I see the following, but I would expect finally block to only be called once.

```
DEBUG GET /
trying
exception caught
finally block
finally block
```
MWE:
```
import jester

routes:
  get "/":
    try:
      echo "trying"
      raise
      resp "never seen"
    except:
      echo "exception caught"
      resp "exception block"
    finally:
      echo "finally block"
```
