Use TetherEnabler in AllInOneTetherSettings to manage master switch

In AllInOneTetherSettings, we use TetherEnabler to hanle all behavior
related to tethering switch on/off.
In TetherEnbler, add WifiManager.WIFI_AP_STATE_CHANGED_ACTION to cover
all possible tethering state change.
TetherEnablerTest is modified accordingly.
