For bucket operations a typical host-style request looks like `bucket.host/`. `HostStyleParser` parses the bucket from host header and appends in the path, by changing the requests to `path-styled`. For bucket operations the original request path is `bucket.host/`, after reconsturction it looks like `/bucket/`: a trailing `/` is added at the end. The PR adds a check to not append this trailing `/` at the end for bucket operations, to keep consistency with path-style requests.
