no-typos crash

[alexlrobertson]

I encountered a crash when linting a file with a bad prop type while using the latest version of the plugin:

MyComponent.propTypes = {
  item: PropTypes.shape()
};

Cannot read property 'type' of undefined

This is a duplicate of #1471 and is fixed in the next release.
