Make auto Wi-Fi summary text consistent with feature availability.

"Turn Wi-Fi on automatically" feature is disabled when airplane mode or
battery saver mode is enabled, when Wi-Fi scanning is disabled, or when
network recommendations are disabled / scorer unset. This change
captures these negative cases in the summary text.
