Title: Object.getOwnPropertyDescriptor called on inherited property causes unhalted TypeError

`connect.middleware` object seems to have 'isString' function in its prototype chain which makes Object.getOwnPropertyDescriptor() to fail. I experienced that after running express 3.4.6 with connect 2.11.2.

```
c:\Users\xxx\express\lib\express.js:48
Object.defineProperty(
^
TypeError: Property description must be an object: undefined
