While disposing a worker script context on worker thread, its corresponding
extension might have already vanished from RendererExtensionRegistry because
of ExtensionMsg_Unload IPC. This means that detecting whether the
script context had extension API bindings installed through
ExtensionAPIEnabledForServiceWorkerScript() won't return correct state.

This CL changes worker disposal to inspect ServiceWorkerData instead,
which should be non null if extension bindings were installed in the
worker script context.
