Changing device pubkey would lead to the stats handling thread panicking. This in turn would cause a reconnect from the gateway side, unnecessarily interrupting VPN sessions.
Currently this situation causes duplicate "VPN Client Connected" events to be emitted, but I decided against fixing this since we'll soon be refactoring our whole approach to VPN client connections (#1701).
Resolves #1671
