wifi_provisioning: Catch the Wi-Fi events even after Connection errors

It was observed that after sending credentials, if the first
Wi-Fi conection attempt fails, the Wi-Fi provisioning managager
ignores subsequent Wi-Fi events. So, even if the device eventually
connects to the AP, the provisioning stays on indefinitely.

Changing a check so that subsequent events are also captured and
provisioning finishes successfully.
