Resolves #556.

a test needs to be fixed, because no more spaces?

db = None, client = <django.test.client.Client object at 0x7f05da1ce7d0>

    def test_project_answers_export_html(db, client):
        client.login(username='admin', ***'admin')
    
        url = reverse('project_answers_export', args=[1, 'html'])
        response = client.get(url)
    
        assert response.status_code == 200
    
        test_file = os.path.join(settings.BASE_DIR, 'export', 'project.html')
        for a, b in zip(response.content.decode().splitlines(), open(test_file).read().splitlines(), strict=True):
>           assert a == b
