Python 3.12.3 -> 3.12.4 breaks use of `create_autospec(X, spec_set=True, name="X")`

Bug report

Bug description:

Hello, thanks for the work you do!

My issue: Updating from 3.12.3 to 3.12.4 breaks many elements in my test suite. We use the name= argument to better understand log messages once a test with many objects fails.

This works with 3.12.3, but crashes with 3.12.4. The issue might have been introduced with this fix: 23ba96e

Code example

File autospec_test.py:

import unittest
from unittest.mock import create_autospec

class X: ...

class TestX(unittest.TestCase):
    def test_x(self):
        mock = create_autospec(X, spec_set=True, name="X")


if __name__ == "__main__":
    unittest.main()

Observed behavior

python 3.12.3

python autospec_test.py
.

python 3.12.4

python autospec_test.py
