Clear the scan list when an empty list is received

When the framework receives an empty scan list from supplicant, it does
not clear the local list. So the UI will continue to show the previous
scan list even when there are no APs around. So clear the local list,
when an empty list is received.

Quicksettings: Few misc adjustements and fixes.

* Fix sleep time tile label on clean flash boot, was showing unknown till you set it in settings.
  Initialize screen timeout with default 30 seconds (wrongly initialized with 0 that is never compared).
* Use switch statement (better performance wise).
* Bit cleanup for wifi ap tile, useless resources reload.
