MQTT trigger functions fail when no arguments expected

[Beiri22]

With the new additions of 1.3. I got a problem, that is easy to work around but may need some attention:

@mqtt_trigger(...)
@state_active(...)
@task_unique(...)
def lueften():
    SOME

no fails with:

2021-02-26 09:20:09 ERROR (MainThread) [custom_components.pyscript.function] run_coro: got exception Traceback (most recent call last):
File "/config/custom_components/pyscript/eval.py", line 697, in call
elif i < len(self.kw_defaults) and self.kw_defaults[i]["ok"]:
TypeError: lueften() called with unexpected keyword arguments: payload, payload_obj, qos, topic, trigger_type

Easy to work around:

@mqtt_trigger(...)
@state_active(...)
@task_unique(...)
def lueften(**kwargs):
    SOME

But it would be handy to also be allowed to not expect any parameter.
