More debugging for issue #7343200 Fails to show wallpaper in the...

...background for lockscreen sometimes and remains black / blank

There was a bunch of state not being put into the dumpsys output.
In particular, the current wallpaper target of the WindowAnimator
was not being included.  I think the problem is that these targets
are not being updated from the main window manager state at some
point where they need to be.
