prop-types false positive outside of component and false negative in component

[billyjanitsch]

Ran into the following issue -- apologies if it's a duplicate; my search of existing issues didn't turn up anything similar.

export const TestComponent = props =>
  <div onClick={() => props.test()} /> // no error

export const mapStateToProps = (_, props) => ({
  otherProp: props.otherProp, // 'otherProp' is missing in props validation
})

Expected: props.test() should throw a prop-types error since TestComponent has no propTypes defined.

Also expected: the props.otherProp in mapStateToProps should not throw since mapStateToProps is not a component.
