[kstyle] Unregister a shadow when it's destroyed

Summary:
Since lifetime of a KWindowShadow doesn't strictly match the lifetime
of the associated widget, we need to unregister the shadow when it's
destroyed in order to prevent accessing or deleting dangling pointers
afterwards.

Comment 4 Nate Graham 2020-01-28 16:22:56 UTC 
I wonder if this is the plasma-integration issue we've been having recently. I was having this before but it went away after I recompiled plasma-integration from source.
