Typeahead with Pre-populated model revisited

[michalgm]

I'm trying to get the typeahead working so that it shows the display label on initialization instead of the value. I found this issue report, #203, which has been resolved.
Indeed, if you use a full object as the value being stored to the model, then the proper label will be displayed when it initializes. However, if you are only storing a single property of the object, you can only display that value.
I've modified the plunker from the previous issue request.

Mind you, I'm like 24 hours new to angular.js, so I may be missing something. However, it seems to me that if you can expect to label->value mapping to function properly when using the typeahead, that the control should initialize with that mapping as well.

@michalgm This is duplicate of #274

Essentially the problem is with results retrieved asynchronously (ex. from a back-end) where we simply might not have enough info to render a label properly, see the discussion in #274 for more details.
