TypeError: Cannot read property 'name' of undefined (complex @returns)

Example:
```js
/**
   * Returns some complex object
   *
   * @returns {{ top: number, left: number }} - [description]
   */
  testFunction(event) {
    return { top: 0, left: 0};
  }
```
Problem in: **utils\parseJsDoc.js**
```js

// instead
tag.type.expression.name 

// add additional checking
(tag.type.expression && tag.type.expression.name) || ''
```
