PFObject's objectWithClassName:dictionary: not doing the right thing with dates

[kangaroo5383]

Example input dictionary:

{
    "confirmationId": "AWKMhXX",
    "data" :  {
        "bookingType": "LB_Access_Entry";
        "units": 1,
        "user" : {
            "name": "new entry person"
        }
    },
    "loungeId": "LB_HQ",
    "reservationTime":{
        "__type":"Date",
        "iso": "2016-06-22T01:37:00.000Z"
    }
}

Running it through + (instancetype)objectWithClassName:(NSString *)className dictionary:(NSDictionary *)dictionary

Output:

<LBReservation: 0x7f8132d22850, objectId: new, localId: (null)> {
    confirmationId = AWKMhXX;
    data =     {
        bookingType = "LB_Access_Entry";
        units = 1;
        user =         {
            name = "new entry person";
        };
    };
    loungeId = "LB_HQ";
    reservationTime =     {
        "__type" = Date;
        iso = "2016-06-22T01:37:00.000Z";
    };
}

Note - reservationTime is just saved as a dictionary instead of converted to NSDate as expected.

There's a straightforward fix of changing its implementation to:

+ (instancetype)objectWithClassName:(NSString *)className dictionary:(NSDictionary *)dictionary {
    return [self _objectFromDictionary:dictionary defaultClassName:className completeData:YES];
}

instead of using a naive assignment as it is doing right now

[dictionary enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
        object[key] = obj;
    }];

If there aren't any other considerations that I somehow missed I can make a PR with those changes.
Thanks!
