Defining `__init__` in model throws `TypeError`

[joeriddles]

Bug

Defining __init__ in a model that inherits from odmantic.Model raises TypeError.

Current Behavior

from odmantic import Model

class MyModel(Model):
  def __init__(self, **data):
    super().__init__(**data)

throws TypeError: __class__ set to <class '__main__.MyModel'> defining 'MyModel' as <class '__main__.MyModel'>

Expected behavior

Defining __init__ does not raise an error.
