    Avoid losing the selection
    
    When the active input sources list is changed in any way (add or
    remove or reorder a source), we write the list to the setting,
    and then we get a changed signal for the setting, and rebuild
    the list from the setting. Doing so loses the selection, unless
    we take extra precaution to keep it.
