"stack" property on HypernovaError is formatted inconsistently
When the error is a Python traceback, each element in the list has a trailing newline:
```python
['  File "/nail/home/ckuehl/pg/yelp-main/virtualenv_run/lib/python2.7/site-packages/pyramid_hypernova/batch.py", line 116, in process_responses\n    response_json = r.json()\n',
 '  File "/nail/home/ckuehl/pg/yelp-main/virtualenv_run/lib/python2.7/site-packages/fido/fido.py", line 98, in json\n    return json.loads(self.body.decode(\'utf-8\'))\n',
 '  File "/usr/lib/python2.7/json/__init__.py", line 339, in loads\n    return _default_decoder.decode(s)\n',
[...]
```

When the error comes from the Hypernova server (a JS traceback), each element has no trailing newline:
```python
[u'ReferenceError: Component "yelp_main__DEV__yelp_main__SearchApp__dynamic" not registered',
 u'at YOUR-COMPONENT-DID-NOT-REGISTER_yelp_main__DEV__yelp_main__SearchApp__dynamic:1:1',

Could we normalize these so that it's easier to print these out in a human-readable way?
