active on DropDown.item and NavDropDown.item is not considered a boolean

[HStokbro]

This will result in an error telling you to not use a boolean, but use boolean .toString() instead. But that's just wrong. Active IS a boolean.

const boolean = true;
<Dropdown.Item active={boolean}>
     {text}
</Dropdown.Item>

(Worked fine in beta-5)

the active prop is being passed through to the DOM node by accident
