False positive for js/react/unused-or-undefined-state-property

[s0]

js/react/unused-or-undefined-state-property doesn't take into account the static method getDerivedStateFromProps.

See example: https://lgtm.com/projects/g/ant-design/ant-design/snapshot/395c5ddd8d3db88e9c34cf332ec77b3c34077cfe/files/components/tag/index.tsx#xf4fd4ef83f04a4fd:1

The state property mounted is read in getDerivedStateFromProps() on line 48.

We merged #607 last week, it adds support for: getSnapshotBeforeUpdate, shouldComponentUpdate and getDerivedStateFromProps. The fix should be online soon.
