disabled prop doesn't work when updating it programatically

[mauriciosoares]

When I update the value from the disabled prop, the component does not react to its change, unless it's unmounted and mounted again. Meaning that if I set disabled to true using a button in the UI for example, the drag and drop functionality is still working.

Here's a example of the bug with the latest version of react-drag-list and a demo I got from the docs: https://codesandbox.io/s/laughing-dew-4gghz
