Unwrap view triggerMethod

This is part two of the unwrap view behavior functionality story.

In this part, we uncover a subtle bug where when a view had behaviors, triggerMethod wasn't returning the view's triggerMethod response. 

Also, it becomes apparent that behaviors' `triggerMethod` doesn't have a return value. Lets talk about it...
@samccone - added the test. It's entirely an integration test in that there's no stubbing - just checks that triggerMethod has a sensible return value when the view has behaviors, which was the scenario that was failing earlier.
