More predictable Downloader::startDownload()

Before this change `Downloader::startDownload()` might avoid starting a new download when a download with the specified URI was already present in its cache. This might be confusing for the following reasons: 1. uri is not the only parameter of `Downloader::startDownload()` - a target download directory may also be specified through the second `options` parameter. Thus calling `Downloader::startDownload()` twice with the same URI but different download directories would not save files into the second directory. 2. Files of a completed download may be removed, whereupon downloading the same files again won't be a no-op. However in such a situation `Downloader` refuses to actually repeat a previous download.
