Fix quick contact icons accessibility issues

Bug: 5275688 accessibility: phone and messaging
     icon both are read as 'image-number' in
     quick-contact card/contact card.

Changed the behavior of ResolveCache.getDescription to get the description
of the action from the icon's app before using the text fields.
