Remove deleted transport objects
Added a QMultiHash which maps transport objects to wrapped object ids. transportRemoved iterates over all matching wrapped objects and removes the passed transport object from their transports-vector. If the transports-vector is empty after removing the passed transport object the objectDestroyed will be called on the wrapped object. transportRemoved will be called either on the transports destoryed signal or on disconnecting the webchannel from it. Without this changes the QMetaObjectPublisher::wrappedObjects and ::registeredObjectIds would only be cleaned up if the website calls deleteLater on QObjects but not on website reloads.
