Subject: [PATCH] Fix signature of assertRaisesRegexp in unittest (#3434)

Fixes mypy false positive `"None" has noattribute "__enter__"` here:

```
class Foo(unittest.TestCase):
    def test_foo(self) -> None:
        with self.assertRaisesRegexp(Exception, "foo"):
            1 / 0
```

Fixes regression introduced in e6c467af8260d9569ca1d3bcb40c3b4bea3fe606.
