Fix appearance changed into wrong activity (#34)

the original `AppCompatDelegate.setDefaultNightMode()` is a global setup. when changing the night mode, it will actually call HomeActivity's `onConfigurationChanged`. this pr tries to set night mode to current activity by using the `setLocalNightMode()`
