3.13.0 jsx-keys Errors

[craigklem]

Using latest version 3.13.0, I see several issues when exceptions in jsx-keys when running eslint with our code. Errors 2 & 3 happen after adding if checks to avoid the exceptions. Could not identify code that made 3 happen - no WebStorm call stack :(

1. TypeError: Cannot read property 'name' of undefined
   line 49 - if (node.callee.property.name !== 'map') {
2. TypeError: Cannot read property 'type' of undefined
   line 54 - var isFn = fn.type === 'FunctionExpression';
3. TypeError: Cannot read property 'argument' of undefined
   line 64 - getReturnStatement(fn.body.body).argument

Code that caused issues:

class MyComponent extends React.Component {
constructor(props) {
    super(props);//number 1 happens here
}
var IconRenderer= function() {
  this.fontsLoaded = false;
  this.checkFonts = function(loadedCallback) {
    this.fontsLoaded = lib.fontsLoaded();

    if (this.fontsLoaded) {
      if (loadedCallback) {
        loadedCallback();//number 2 happens here
      }
}
