Fix a typo

[liebo]

ExportClosure can not return any exportable instance, dig into the source code, find it may be a typo.

Thanks for the contribution, I have to dig into the issue to have a clearer idea about the problem.
Maybe a test for this issue, considering both exportclosures and other exportable cases?

I found that this fix still didn't work for me; I had to return r (and not r.g) for my use case.

Basically the simple version of my test (which is contained in a bunch of domain-specific code that I can't share) is as follows:

@Export
public class SomeExportedObject {
    public string someField;
}

@Export
@ExportClosure
public interface IGetter {
     SomeExportedObject get(String arg);
}

@Export
public class GetterCaller {
    private IGetter getter;
    public GetterCaller(IGetter getter){
        this.getter = getter;
    }

    public void callGet(String arg){
        SomeExportedObject obj = getter.get(arg);
        String foo = obj.someField;  // this line is where the error happens 
    }
}

js code:

var mock = function(arg){
    var ret = new com.mypackage.SomeExportedObject();
    ret.someField = arg;
    return ret;
}
var getterCaller = new com.mypackage.GetterCaller();
getterCaller.callGet('hello world!');

With the version in @manolo repository, this yields (in chrome dev console):

obj is not defined

With the version in @liebo repository, instead, obj.someField exists, but is empty.

With the version in @svtdragon repository, obj.someField == 'hello world'.

(Worth noting: r.g has the right fields for a SomeExportedObject, but they are empty/default. r.g.g has the correct values-- r.g.g.someField == 'hello world!')

my code is something like this:
@export
@ExportClosure
public interface IGetter {
void doSomething(Expotable someExportableObject);
}
in javascript implemention of doSomething：r.g instead of r returns the correct wrapped exportable object.
