Pepper: Simplify FileDownloader::url().

The current behavior of FileDownloader::url() is strange since the value
changes after the initial GET request. I've found this a little awkward, and
decided to make url() always return the url passed to FileDownloader, and
full_url() return the extra url information from the GET request.
