GmailMaildir.py Removed __init__

First, in Python 3 we don't need call the super().__init__ explicitly, because Python does it. So, we can remove the line:

super().__init__(reposname, account)

If we leafe the method __init__ empty, the parent __init__ method is not called, we need remove the __init__ and then Python uses the parent __init__ method.
