By default, the OpenHTF base logger propagates until initialize_record_logger is called

The problem is that `configure_cli_logging` does not configure the `openhtf` logger if `CLI_LOGGING_VERBOSITY` is `0`. The `openhtf` logger will be configured later once `initialize_record_logger` is called.

This can cause stray logs to appear if an OpenHTF user adds handlers to the root logger before the first `TestState` is created.

**Example:**

Add:

```python
import logging
logging.basicConfig(level=logging.DEBUG)
```

...to hello_world.py at the top of the main block. Then the following log line appears at the start of the test run:

> INFO:openhtf.core.test_descriptor:Executing test:
