Fix type of data parameter in get test requests

[nils-van-zuijlen]

Lists of two-tuples of strings are allowed in the data attribute for get requests

Example of a false-positive needing this fix:

        factory = ApiRequestFactory()
        request = factory.get(users_list_url, data=[("manager", manager1.username), ("manager", manager2.username)])

The import paths seem to be wrong in the original code, hence why the tests are broken.

The CI has been fixed

CI fixed again, sorry! I rebased your branch.

LGTM!

Thanks for the PR

A similar change would be helpful in django-stubs as well for the RequestFactory class and django.utils.http.urlencode function.

The lint and test are failing because an import is missing for Mapping, Iterable

But typecheck fails due to changes in upstream DRF tests; I'll fix that in a bit.

From typecheck output

drf_source/tests/test_pagination.py:546: error: Argument 2 to "get" of "APIRequestFactory" has incompatible type "Dict[str, int]"; expected "Union[Mapping[str, Union[str, bytes, Iterable[Union[str, bytes]]]], Iterable[Tuple[str, Union[str, bytes, Iterable[Union[str, bytes]]]]], None]"

Maybe we should accept int as well? It's weird to pass URL params as integer, but on the other hand, this does work and is covered by unit tests.

If there are still remaining typecheck errors after that, we should just suppress them via IGNORED_ERRORS.

Sorry, I've neglected this project a bit while I focused on django-stubs. Rest assured, I haven't forgotten about it. :)

[intgr]

I rebased your branch, there are some false positives in CI typecheck which shoud probably be added to ignores list.

[intgr]

I pushed the relevant typecheck ignores and this can now be merged. Thanks!
