IoT first Wifi connection failed

[tidjidi]

Hi team,
I made some Arduino cloud experiences, and discovered that systematically, the first Wifi connection trial failed, while the second is always fine. Very odd!
Thanks to DBG_VERBOSE mode, I noticed that Wifi Ids (SSID, PASS) are not loaded the first time...

So, digging a little bit in the libraries (ArduinoIoTCloud and Arduino_ConnectionHandler) to find my way, I created a patch to avoid this situation (maybe it's not the optimal solution, but for me it does the job! And that's fine).

Within the file WiFiConnectionHandler.cpp, in the method WiFiConnectionHandler::update_handleInit(), I added this short test (line 95 in release1.2.0 - within the test if (WiFi.status() != WL_CONNECTED)):

  if (WiFi.status() != WL_CONNECTED)
  {
     if (strlen(_settings.wifi.ssid) == 0) {
      DEBUG_ERROR("Network settings absent");
      return NetworkConnectionState::INIT;
     }
...

And as it worked with that patch, I didn't look further to find a reason why Wifi Ids are not received at that stage!

Thanks for all.
