altTab: Don't error out if we don't have windows for an app
We are currently erroring out when the tab chain doesn't contain at least one window for an app which might happen for windows that don't take focus like xeyes. This leaves us in a state where we can't show the switcher at all. Let's just ignore these apps instead of looking broken.
