fix: use module logger instead of root logger in b_aiosqlite.py

All other persister modules in burr/integrations/persisters/ use
logging.getLogger(__name__) to create a properly scoped logger.
b_aiosqlite.py was using logging.getLogger() (no arguments), which
returns the root logger.

Using the root logger is bad practice because:
- It causes log messages to bypass the module's namespace, making it
  harder to filter or configure logging for this specific module.
- It can lead to unexpected log output appearing in the root logger's
  handlers even when the module's logging is intended to be suppressed.

This one-line fix changes it to logging.getLogger(__name__) for
consistency with all other persister implementations.
