Fixed issue with incorrect public URLs sent with the video_copied_s3 webhook for S3 buckets with dots in their name

If your S3 bucket had a dot in the name, the URLs (url, rawRecordingUrl, snaptshotUrl, filmstripUrl) sent through the video_copied_s3 webhook would be incorrect as they missed the bucket name. This happened across storage services, regardless if you used S3 buckets from AWS or S3 API compatible storage.
