test: port downloader/installer/io/json/event-dispatcher/functional stubs

All ignored: these mock IO/HttpDownloader (curl)/ProcessExecutor/installers,
use ZipArchive/JsonManipulator todo!()s, need Symfony console or schema
validation, reflect into ClassLoader, or run end-to-end install/functional
fixtures. Wires up the event_dispatcher test target.
