Title: Undefined values hashing

```javascript
var obj = {
key: undefined
};
```

When I'm trying to create a hash from object what contains undefined value:

```
TypeError: undefined is not a function
at Object.dispatch (/Users/harri/Projects/Repos/object-hash/index.js:94:48)

at Object.next [as _onImmediate] (/Users/harri/Projects/Repos/object-hash/node_modules/tape/lib/results.js:66:15)
```

Serialising undefined value solves the problem.
