    Don't pass configure events on the composite overlay window to MetaStackTracker
    
    When the screen resizes, we get a configure event for the composite overlay
    window - don't pass that to MetaStackTracker, since the COW isn't in the
    stack.
    
    Fixes warning:
     mutter-WARNING **: STACK_OP_RAISE_ABOVE: window 0x65 not in stack
