Fix: use-after-free after ClientNetworkCoordinatorSocketHandler::CloseAllConnections() (#9534)
The function clears all stun-handlers. This causes all of those objects to be destroyed. A handler can have a pending connecter, which was only killed in case CloseConnection() was called. This is never the case when the object is destroyed. In result, the connecter could finish and cause a use-after-free by calling into the (now deleted) handler.
