handleFieldChange returns whatever controlled "onChange" returns as the next field state

[kettanaito]

Environment

• react-advanaced-form: 1.6.5

What

Current behavior

react-advanced-form/src/utils/handlers/handleFieldChange.js

Lines 35 to 47 in 9c17655

	return dispatch(
	onChange,
	{
	event,
	nextValue,
	prevValue,
	fieldProps,
	fields,
	form,
	},
	form.context,
	)
	}

This returns anything controlled change handler returns (i.e. async action). Later, depending on the returned payload from the handleFieldChange handler, Form.handleFieldChange dispatches its updateFieldWith.

react-advanced-form/src/components/Form.jsx

Lines 452 to 454 in 9c17655

	if (nextFieldProps) {
	await this.updateFieldsWith(nextFieldProps)
	}

This results into returned payload set as the field's state, which is wrong.

Expected behavior

• Only valid field state is set in the field's state

How

• Dispatch the onChange handler first, then return short-circuit
