Write a negative test for ajaxify confirmation message

Problem/Motivation

We are already doing a positive test that the confirmation message appears when product is added to cart. It would be better for the quality of this module, if we also add a negative test.

The negative test will be like testAjaxAddCartForm(), and it would check whether the confirmation message is indeed ajaxified.

Right now, it is throwing error (base table or view not found search_total) if a negative test is run. I didn't spent much time debugging the problem. I think the problem is with standard profile, because a similar testAjaxAddCartForm() is working alright if run on testing profile.

Proposed resolution

Add negative test.
