    window: Fix false null dereference warning
    
    Clang’s scan-build tool complains:
    
        ../../../src/fr-window.c:7320:10: warning: Access to field 'data' results in a dereference of a null 
pointer (loaded from field 'history_current') [core.NullDereference]
                        return private->history_current->data;
                               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    
    But we are already calling `fr_window_history_add` on the previous line,
    which updates the `history_current` with the new location.
