Fix a crash when a script generates a Fg/BgColor change when closing the app 

If a script Dialog changes the app.fgColor/bgColor in its onclose
callback, it will notify all fgColor/bgColor preference
observers (ContextBar is one of them), if we don't disconnect from
these signals when we're deleting ContextBar, the signals will call a
deleted slot/connection from app::script::close_all_dialogs().
