Can't use .once more than once.

I can confirm that changing unset_once_if_written to:

@export
def unset_once_if_written():
    """Unset the once file, if it has been written to."""
    global once_file, written_to_once_file
    if written_to_once_file:
        once_file = written_to_once_file = None

fixes the issue. Clearing written_to_once_file makes sure that the trigger doesn't fire forever for later commands.
