python: no completion for controller.A.on_event

[jwunderl]

Describe the bug

Python autocomplete (maybe js too, am in a python tutorial) seems to think controller === controller.A and only gives options like .any_button

To Reproduce Steps to reproduce the behavior:

1. Go to a python project
2. type controller.A
3. expect to see on_event
4. See error

Expected behavior

should get a valid completion

[shakao]

javascript completion for controller.A.onEvent results in code with error:

controller.A.onEvent.Pressed, function() {
    
})
