Fix a couple of issues with mOpeningApps.

In setAppVisibility add wtoken to mOpeningApps even if the requested
visibility already matches requestedHidden. When Keyguard hides an app
requestedHidden will mismatch and mOpeningApps will end up empty where
it should have the app that will become visible.

Add mAnimateWallpaperWithTarget = true to another situation where
wallpaper animation needs it.

Fixes bug 11570753.
