Ion-item activated styles being overriden

@mhartington

Hi. I added a background color to my ion-item like,

<a ion-item color="mycolor"></a>

The background color gets applied. But the activated color when you tap on the <a ion-item> is being overriden by a default style. When I inspected,

.item-ios-mycolor.activated {} is being overriden by .ios .item.activated {}

Is this a bug? This happened after upgrading my app to “ionic 2.3.0”
