Currently the only client of clear method is WorkerScriptController (this
method is called in dtor.)

I believe that as worker most probably would own a separate V8 instance, VM
destroy should take care of clearing (if it's not the case, I'd be glad to fix
it on V8-side.)

If this cleanup is crucial, I'd provide a separate method to iterate through
created wrappers.

This patch is just one in (planned) series of patches which could lead to
elimination of indirect reference from the Node to its wrapper.  The next move
would be to get rid of visit which is somewhat more involved.
