    switcherPopup: Use roundtrip time when the popup is modifier-less
    
    The noModsTimeout obviously finishes inside a timeout callback, which
    means `global.get_current_time()` might return Clutter.CURRENT_TIME (ie.
    0) when called inside it, because it's not called while handling an
    event. This means when switching apps or activating a window, the
    timestamp passed to `activate_window` may be 0, which is the reason why
    the altTab switcher is currently broken when using modifier-less
    keybindings.
    
    Fix that by using `meta_display_get_current_time_roundtrip`, which
    always return a valid timestamp, instead of
    `shell_global_get_current_time`.
