App 2.17.2: Wi-Fi auto-connect removed

Upstream kept the head unit on the driver's phone hotspot by re-joining
a saved network every few minutes. This car's head unit has its own
connection and the Wi-Fi is not used, so the feature goes entirely:
WifiAutoConnect, its call on the service tick, the preference key, and
the ACCESS_WIFI_STATE / CHANGE_WIFI_STATE permissions.
