fix: align test assertions with actual template implementation

Update test_template_handles_non_registerable_modules to check for the
actual exception handling pattern used in _AGENT_ENGINE_APP_TEMPLATE:
- Changed assertion from "except Exception:" to "except Exception as e:"
- Changed assertion from "pass" to "_logger.debug" to match the logging
  behavior in the template
