LockscreenInterface from ToggleLockscreenTile (Part 1 of 2)

The current longpress intent of the lockscreen tile is to open
the security settings activity. However, all lockscreen options
were moved to their own fragment months ago. This fixes the
tile longpress to open the current lockscreen options.

Restore list preferences from system preference instead of currently used values

WiFi country code and frequency band are updated only when wifi is restarted.
Restore values to the list preferences from Settings.Global to convince the
