[Fuchsia] Explicitly inform Modular if a WebComponent's Frame goes away.

WebComponent tears down if the Frame disconnects, but this will result
in a blank Mod being displayed, unless Modular is explicitly requested
to remove the WebComponent from the Story.

base::fuchsia::StartupContext teardown is fixed in the case of services
being received via |LaunchInfo.additional_services|, and the
WebRunnerSmokeTests are fixed to provide at least an empty service-
directory to the launched WebComponents.
