Multiple Tagging with "Array of object" is allowing insertion of duplicate entries. #1820
Description
Bug description:
I created tagging feature, where user can select from existing stored tags or create new if not existed. So if I have one tag "Algorithm" in dropdown, and user type "algo" then it allows creating new one. But if user type "algorithm" or "Algorithm", then both existing tag and "create new" displays. So it should allow insertion of new tag only if it is not already existing tag.
This is the array, which populates the ui-select:
[ {uid: "0x943835545", name: "Algorithm"}]
Probably it should allow to filter on one property of object, for example name of the tag and ignore others. And if tag name exist then "Create new" label should disappear or disabled.

This is happening on official Tagging example as well. This is someone else's plunker link. Check array of object example.
