[Bug 3205464] - handle [wm forget] when the parent is unmapped on windows
The fix for [Bug 2009788] prevented a crash but causes windows to be lost if their parent is unmapped when [wm forget] is called. Added a test for this case and ensure that the parent window exists when we remap the child to its parent.
