Now that downloadruntimes can download and unzip .tar.gz files, it also needs to be able to properly point to the new root folder of the unzipped location. So if a .tar.gz file is /home/rob/tmp/some.tar.gz, and it expands to /home/rob/tmp/my-app-version-2.3.0/ with all files under that, it should correctly identify that new folder as the root of the unzipped archive.
