Subject: refactor(http-downloader): wrap HttpDownloaderMockState in
 Rc<RefCell<>>

In prep for the upcoming &self conversion of add()/get()/copy(), the
mock hook needs interior mutability too. The struct's Clone derive is
dropped since nothing clones the whole state anymore, only the shared
Rc handle.
