2nd attempt to fix Slice strict mode.

Browse Source 
1. Use real BluetoothAdapter instead of settingslib version. The
   settingslib version contains calls that violates strictmode rules.
2. Override StrictMode rules in SettingsSliceProvider when it's called
   in background thread. When in background, the enforcement from Slice
   framework (StrictMode#ThreadPolicy) is not useful and can be safely
   ignored.
