Lib2to3 does not support changes made in https://bugs.python.org/issue32117

```python
def test():
    my_list = ["value2", "value3"]
    yield "value1", *my_list
    return "value1", *my_list
```

The idea is to use `testlist_star_expr` instead of `testlist`.

This is a backwards compatible change, because testlist_star_expr supports test as well like testlist does.
