state_trigger not working after disabling and reactivating pyscript

[rumpeltux]

I believe the culprit is here in __init__.py:

    async def hass_started(event: HAEvent) -> None:
        _LOGGER.debug("adding state changed listener and starting global contexts")
        await State.get_service_params()
        hass.data[DOMAIN][UNSUB_LISTENERS].append(hass.bus.async_listen(EVENT_STATE_CHANGED, state_changed))
        start_global_contexts()

The state_changed listener is only setup upon hass_started.
When disabling pyscript, the listener is removed. When re-enabling it, the listener is never re-added.
