Bug 1070731 - [sms] unit test refactoring for new version chai.assert api

test_agent used very old version chai library version=0.5.3
in the current version=1.9.1 deepEqual take prototype into consideration

apps/sms/test/unit/localization_helper_test.js - plain structure
I'm not sure why you rewrote most of this file. I think Oleg tried to factorize most of these tests to avoid some copy/paste, and I think we should try to stay the same. Oleg will help you doing some better code here.

Thanks
