multiple inheritance requires to **kwargs in any case

[AnNeub]

If using multiple inheritance than the **kwargs need to be generated independent from eSuperTypes

{%- macro generate_class_init_args(c) -%}
    {% if c.eStructuralFeatures | list  %}, *, {% endif -%}
    {{ c.eStructuralFeatures | map(attribute='name') | map('re_sub', '$', '=None') | join(', ') }}
    {%- if c.eSuperTypes %}, **kwargs{% endif %}
{%- endmacro %}

{%- macro generate_super_init_args(c, user_module=False) -%}
    {%- if user_module and c.eStructuralFeatures -%}
    {{ c.eStructuralFeatures | map(attribute='name') | map('re_sub', '(.+)', '\g<0>= \g<0>') | join(', ') }}
    {%- endif %}
    {%- if c.eSuperTypes %}{{', ' if user_module and c.eStructuralFeatures else ''}}**kwargs{% endif %}
{%- endmacro %}

Following use case:

class A
  aattr1
  aattr2

class B 
 battr1
 battr2

class C(A,B)


C(aattr1=1, battr1=2)

A.__init__ looks like this def __init__(self, *, aattr1=None, aattr2=None)
This lead to the problem that A.__init__ is called with a keyword argument (battr1) which is not known by the init function.
