fix(wm): make close + min op on foreground hwnd

This commit changes the handlers for the Close and Minimize
SocketMessages to operate on the output of
WindowsApi::foreground_window, without checking the window manager state
as it was doing previously.

This will allow the commands to operate on any kind of managed or
unmanaged window, and the appropriate WinEvent will be emitted by the
closed window for the window manager state to be updated when the
WinEvent goes through process_event.

fix #839
