Doesn't update on connection lost

[moisoni97]

While connected to wi-fi, if I pull out the internet cable from the router the listener doesn't detect that the internet connection is lost. It still returns true on isConnected. Restarting the app makes the listener return the real state of the connectivity.

I've tested it on a "new-test-project" only to see how it works following the code you provided in ReadMe.
