When the S3 store was enabled, we were only applying the S3 CDN. So all images stored locally, like the emojis, were never put on the local CDN. Fixed a bunch of CookedPostProcessor test by adding a call to 'optimize_urls' in order to get final URLs. I also removed the unnecessary PrettyText.add_s3_cdn method since this is already handled in the CookedPostProcessor.
