Frameworks: privacy guard fix UI freeze

randomly sometimes the complete UI freezes when toggle
privacy guard. Move out the forcekill from syncronized to
fix it so that it kills the app when all threads are open
and they can react to the forcekill which cannot result then in unknown states

cheers

Profile: Filter on NETWORK_STATE_CHANGED instead of SUPPLICANT_STATE_CHANGED

For more reliable network change detection use NETWORK_STATE_CHANGED
instead of SUPPLICANT_STATE_CHANGED

Only set profile when profile actually changed.
Use getWifiSsid instead of getSSID so we dont have to strip double
quotes ourselves, add null pointer exception check because function can
now be called when WiFi is off.
