[feature request] no-undef for undefined class component methods

Something that detects undefined class methods would be useful. Currently, this passes undetected:

class MyComponent extends React.Component {
    onTap = () => {
        this.undefinedMethod()
    }
    render = () => {
        return <Button onTap={this.onTap}>
    }
}
