Fix shell transition for showWhenLocked + translucent activity.

Fix two issues if AOD is disabled:
- There should request to adjust wallpaper target after
  ActivityRecord#commitVisibility. The NotificationShade can
  accidentally be wallpaper target when AOD is enabled.
- If resumeTopActivity happen eailer than DisplayPolicy#setAwake, there
  will no transition to collecting the resuming activity, try to
  request a wake transition before resume top activity if default
  display is not awake. When AOD is enabled, usually setAwake will
  be called earlier.
