setIcon() not working on IconicsImageView
Hello Mike,

Thanks for this nice library!

Just updated to
```
compile 'com.mikepenz:iconics-core:2.9.1@aar'
compile 'com.mikepenz:iconics-views:2.9.2@aar'
compile 'com.mikepenz:google-material-typeface:3.0.1.1.original@aar'
```

I'm using your FastAdapter library. The AbstractItem has three IconicsImageViews in it's layout resource. Two of these icons are defined in xml and show up correctly in the RecyclerView. However on one IconicsImageView I set the icon dynamically the onBind method. But with the newest version of Iconics library, setIcon(IIcon) is not working for me, the icon doesn't show up.

The icon's xml looks like this

```
<com.mikepenz.iconics.view.IconicsImageView
android:id="@+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:iiv_color="@color/white"
app:iiv_size="28dp" />
```

And I'm using `viewHolder.icon.setIcon(icon);` whereas icon is an IIcon.

Any ideas?

Thanks and best regards,
Rob
