Title: S3DownloadHandler: fix auth for requests with quoted paths/query params

The problem is that `p.path` and `p.query` strings are already url-quoted upon
entering `download_request` method, but they are url-quoted for the second time
inside `conn.make_request` and thus signature is generated for doubly-quoted
string. If the extra level of quoting is removed, everything works fine.
