Hide the nav handle when going to AOD rather then having it stay there, change color, then disappear.

This has annoyed me for a very long time and is now very easy to fix.

Bug: 278086361
Flag: com.android.systemui.keyguard_wm_state_refactor
Test: go to/from AOD from GONE/LS, ensuring the handle re-appears on LS/GONE
