Object passed to on-tag-added with use-strings="true"

[cgatesman]

If you use use-strings="true" along with on-tag-added (or other callbacks), the $tag passed to the onTagAdded($tag) function is an object (e.g. {text: 'Tag Name'}) instead of just the tag name string. In addition to this, on the first tag add, the tagsInput model within the onTagAdded($tag) function call is an array of objects instead of an array of strings. On additional adds, the model in onTagAdded($tag) is the correct array of strings; however, it is missing the newly added tag.

One thing to note: If you put a $timeout in the onTagAdded($tag) function, the model is always correct after the $timeout.
