MR Python client get_registered_models inf loop scenario

[tarilabs]

Describe the bug
infinite loop when registered models are less than default first page

To Reproduce

@pytest.mark.e2e
def test_get_registered_models_no_next_token(client: ModelRegistry):
    models = 3

    for name in [f"test_model{i}" for i in range(models)]:
        client.register_model(
            name,
            "s3",
            model_format_name="test_format",
            model_format_version="test_version",
            version="1.0.0",
        )

    for model in client.get_registered_models():
        print(model)

notice only 3 registered model.

running with

poetry run pytest --e2e -s -k test_get_registered_models_no_next_token

exhibits the follow in the logs:

... (goes on forever)

Expected behavior
No infinite loops.

Additional context
Please notice when number of entities is above the default page size,
a nextPageToken is passed in the second list-call,
etc,
and empty nextPageToken is passed in the last-call terminating.

ie.

... and terminates successfully.

this is all I've observed so far.
