Remove re-export of local_uuid

Before this patch, the `pytest` calls in unit testing raise the
`DeprecationWarning` from `case_utils.local_uuid`.  E.g. both of these
test files would raise the warning:

(test1.py)

```python
def test_foo() -> None:
    import case_utils
```

```bash
pytest test1.py
# Logs deprecation warning.
```

(test2.py)

```python
import case_utils
def test_foo() -> None:
    pass
```

```bash
pytest test2.py
# Logs deprecation warning.
```

This patch removes the module re-export.
