fix: TypeError unexpected query set model, compare correct object type, for version 7.4

[jhonvidal]

I am using django-elasticsearch-dsl version 7.4 and I want to contribute with this correction that caused the following problem:

TypeError at /en/search/

Unexpected queryset model (should be: <class 'myshop.models.Product'>, got: <class 'myshop.models.Product'>)

As a consequence and cause of this implementation:

def filter_queryset(self, queryset, keep_search_order=True):
    """
    Filter an existing django queryset using the elasticsearch result.
    It costs a query to the sql db.
    """
    s = self
    if s._model is not queryset.model:
        raise TypeError( …
            'Unexpected queryset model '
            '(should be: %s, got: %s)' % (s._model, queryset.model)
        )
    # Do not query again if the es result is already cached
    if not hasattr(self, '_response'):
    
    
    Verifying and debugging we observe that the variables are different :
    

We observe that the models are not the same, it is because they are not showing the correct thing.

The solution is to add ._wrapped after ._model
