Don't start fading when screen is unredirected

Browse Source 
If a window is destroyed and starts to fade out when screen is
unredirected, when the screen become redirected again, we will generate
errors when trying to render that window.

Also make sure the assumption that all window are either MAPPED or
UNMAPPED when screen is unredirected holds.
