Describe the bug

event.value is not consistent when there is empty value selected with the dropdown.
The value getting returned is an object instead of a string

Steps to reproduce the behavior

1. Click on the dropdown item "All".
2. Observe the e.value returns as {name:"All",value:""}
3. Click on the dropdown item "Active".

Bug is right here:

primereact/components/lib/dropdown/Dropdown.js

Lines 827 to 831 in e47f620

	const getOptionValue = (option) => {
	const optionValue = props.optionValue ? ObjectUtils.resolveFieldData(option, props.optionValue) : option ? option['value'] : ObjectUtils.resolveFieldData(option, 'value');
	return ObjectUtils.isNotEmpty(optionValue) ? optionValue : option;
	};

I think line 830 should be changed to:

return props.optionValue ? optionValue : option;

and that would fix bugs with empty string and null dropdown values
