  1. Fix closure compiler error

    I'm trying to fix some bugs in the Closure compiler template type
    checker. The fix has revealed a type error in shadydom, which this PR
    attempts to fix.
    
    With the fix, the following error occurs:
    
    ```
    shadydom/src/patch-events.js:286:53: ERROR - [JSC_TYPE_MISMATCH] actual parameter 3 of Object.defineProperty does not match formal parameter
    found   : ObjectPropertyDescriptor<Event>
    required: ObjectPropertyDescriptor<(Event|{
      composed: ?,
      composedPath: function(this:Event): ?,
      relatedTarget: ?,
      stopImmediatePropagation: function(this:Event): undefined,
      stopPropagation: function(this:Event): undefined,
      target: ?
    })>
      286|     /** @type {!ObjectPropertyDescriptor<!Event>} */ ({
                                                                ^^
      287|       /**
           ^^^^^^^^^
    ...
      296|       configurable: true,
           ^^^^^^^^^^^^^^^^^^^^^^^^^
      297|     })
           ^^^^^^
    
    ```
    
    This error is correct because EventPatches is an object literal, which
    can never be an Event because Event is a nominal type in Closure.
    
    I think this change should be OK and will unblock Closure compiler
    fixes.
