Unregisters a previously registered message handler in script world with name world_name.
If null is passed as the world_name, the default world will be used.
Note that this does *not* disconnect handlers for the
#WebKitUserContentManager::script-message-received signal;
they will be kept connected, but the signal will not be emitted
unless the handler name is registered again.
