IconicsImageView doesn't reflect iiv_color
`androidIconics = '2.9.1' // https://github.com/mikepenz/Android-Iconics`
core + views

```
<com.mikepenz.iconics.view.IconicsImageView
                android:id="@+id/icon_email"
                android:layout_width="50dp"
                android:layout_height="50dp"
                android:background="#29d09e"
                android:padding="15dp"
                app:iiv_color="@color/white"
                app:iiv_icon="ANY_ICON"/>
```

Icon color is black, not white.
Before we used `2.8.9` and it works as expected. Must be regression.
