Pass "data" as a keyword argument when instantiating form_class

[lassebomh]

I ran into a problem using AuthenticationForm as form_class in UnicornView due to the extra request argument in the forms constructor. This caused form data to be passed incorrectly in _get_form and was fixed by simply changing "data" to a keyword argument.

My component:

from django_unicorn.components import UnicornView
from django.contrib.auth.forms import AuthenticationForm

class AuthenticateView(UnicornView):
    form_class = AuthenticationForm
    
    username = ""
    password = ""

Cause the error:

'AuthenticationForm' object has no attribute 'cleaned_data'

While not necessarily condoning the use of authentication forms with unicorn, a temporary fix to a problem like this can be solved by inheriting the form class and changing init, like this:

class AuthForm(AuthenticationForm):
    def __init__(self, *args, **kwargs):
        super().__init__(None, *args, **kwargs)

class AuthenticateView(UnicornView):
    form_class = AuthForm
    
    username = ""
    password = ""

Great work on Unicorn by the way
