* Added GraphQLTransactionTestCase
- Adds support for testing code that is executed within a transaction
Reference: https://docs.djangoproject.com/en/3.1/topics/testing/tools/#django.test.TransactionTestCase
```
For instance, you cannot test that a block of code is executing within a transaction, as is required when using select_for_update(). In those cases, you should use TransactionTestCase.
```

Without explicitly setting the encoding to "utf-8" I get the following error on windows (python 3.9)
```

I think it might be helpful to add an explicit hint that HTTP headers should be prepended with `HTTP_` as required by `django.test.Client` (at least it was not super obvious to me when I tried to use it).
* Use the Django Client test utility instance that Django provides with its TestCase class. This allows GraphQL tests to make use of the stateful client methods like login()
* Add missing test case initializer call
* Don't break backward compability
* Add test for pending deprecation warning on GraphQLTestCase._client

* fix( DjangoListField ): test that default functionality should resolve/call queryset at view time, first attempt at solution
* fix( DjangoListField ): DjangoListField defines get_manager just like DjangoConnectionField for a better variable name default_manager instead of default_queryset
* fix: apply specific black formatting
In general I welcome reviews even from non-maintainers to build confidence. I haven't seen any objections and this has sat with approval for a week so I am going to go ahead and merge.
* Add a default msg to show the response content.
This seems like an issue with using assertResponseNoErrors and assertResponseHasErrors
Which doesn't include any errors specific to the response and currently just shows.
```python
self.assertNotIn("errors", list(content.keys()))
AssertionError: 'errors' unexpectedly found in ['errors', 'data']
```
* Update testing.py
