Within a client, if all of the subscriptions on the global messenger are cleared while lookupNetwork on the NetworkController is being called, it can cause the messenger to throw an error when lookupNetwork attempts to unsubscribe from the NetworkController:networkDidChange event. This happens in Mobile when destroying the engine. We should account for this.
