super for `object` does not work

Having sp.py file with code

```
class Test(object):
    def __init__(self):
        super().__init__()

t = Test()
```

And running with Micro Python

```
$ ./unix/micropython sp.py
Traceback (most recent call last):
  File "sp.py", line 5, in <module>
  File "sp.py", line 3, in __init__
AttributeError: 'super' object has no attribute '__init__'
```

Above works with CPython.
