Subject: [PATCH] When polling, raise if an error is returned

Previously, if an error from the API was returned while polling for updates on a file, it would continue polling. I updated it so that it raises a RequestError if the API returns an error status. If not, it raises a RetryError, which is swallowed by the retry gem's `with_retries` block.

Example of an error that led to continued polling:

```
{"status":"error","error":"File validation error: Uploading of these file types is not allowed.","error_code":"DownloadFileValidationFailedError"}
```
