Filter 'filter' bugs when values are null

As described in here: #1780

@alexandernst what version of AngularJS did you try? It seems to be OK with the latest released (1.2.13):

@pkozlowski-opensource I'm using 1.2.13: http://plnkr.co/edit/UzUbnECIBqJ9BOLprnw6?p=preview

Anyways, I just realised that maybe I'm wrong. Take a look at lines 20 and 22. That is a comparator function that should be called (and it is called) and that returns true always. Should that make it return all the objects, or the {desc: ''} gets higher priority?

Thanks @alexandernst for bringing this up. I'm going to reopen #1780 as there are a number of people there who think it's an issue. Thanks @pkozlowski-opensource for reproing with 1.2.13.
