Deselect should maintain previously selected wallpaper and guest should load default guest wallpaper

Deselect should maintain previously selected wallpaper and select guest user should use default guest wallpaper


Deselect user from user pod should not set the wallpaper to a white background. It should use whatever wallpaper is showing.

It also fix the problem when selecting guest user pod, the wallpaper didn't set to default guest user wallpaper.

Hi Nikita.

could you please take a look? 

Wallpaper stay as white wallpaper when new wallpaper index = current wallpaper
index. 
We should redraw wallpaper but not reload wallpaper data in this case. 

Thanks

Hi Nikita.

Pre discussion:

Now the deselection didn't do anything.
and click on guest user will show the default guest wallpaper.

"add user" needs to be treated in a separate CL.

could you please take a look? Thanks.
