Apply `default` property to event fields about glee HOT 4 OPEN

@fmvilas what do yu think we should try to do ? the code should not fail if the event.payload.repeat is undefined.we are trying to solve this only right?

@Min2who I think the problem here is a little more complicated.
IMO we need to follow the following approach whenever we are dealing with schemas and the "data" that we validate against that schema.

1. load the defaults from the schema.
2. Deep merge the loaded default to the "data" giving priority to the "data" itself.
