(EVK) Initial provisioning fails over Ethernet

[nseidle]

The device should use ethernet, if available, to provision/update keys during POR.

To replicate:

• Factory reset
• Disable network failover
• Set default network to ethernet
• Enable PointPerfect
• Exit menus to save settings
• Reset the device

Device will fail to provision because in States.ino the line:

else if (wifiNetworkCount() == 0 && strlen(settings.pointPerfectCurrentKey) == 0)

is WiFi centric.

Instead, we should check for ethernet connectivity as well and enter STATE_KEYS_PROVISION_WIFI_STARTED (please rename states as needed) or add states to start ethernet.
