    Avoid harmless warning trying to split None autostartcondition
    
    When self.get_austostart_condition() returns None and
    autostart_type is not None, the following code will
    try to apply split on None.
    The exception handling catches this and returns the correct
    value for the function in this case so it's harmless,
    this just fixes so that there's no traceback in the application
    output....
