Title: cast $meta_values as array

I was trying to pass a variation's attributes to the `display()` method of `WC_Order_Item_Meta` and was getting invalid foreach statements on line 50:

```
foreach( $meta_values as $meta_value ) {
```

I guess the actual meta has an array, but the attribute's $meta_values were a string.
