[r7373] Close windows with a schedule opened closes pinned windows

[gauthier]

Simutrans 120.0.1, pak128 2.5.2.

Open any window and pin it. Open a vehicle's schedule window. Close windows with backspace, the pinned window is closing too.

r7381 should fix. Very very ugly hack fix, but works in this specific case. Windows mustn't close themselves while they're being closed!

Thanks I am testing this as soon as possible.

EDIT: looks like it is fixed, thanks a lot !
