reorder tests to prevent stack overflow in IE, switch from Zepto to jQuery

Removing everything from the tests but
```
describe('costanza', function() {                                        
  describe('costanza#onerror', function() {                                        
    // ..this one specific test
  })
})
```
still shows overflow. Certainly could be a state issue, however at that point I am not sure what state would be changing it.

it does. the addEventListener is coming from mocha

Haven't debugged IE 8 yet, other than getting the suite to run. `attachEvent` is used in mocha
