refactor: Use pytest caplog instead of logger patching in test_spec.py

[DevCube24]

This PR addresses issue #37468 by refactoring the test test_get_exception_returns_empty_list in api/tests/unit_tests/controllers/console/test_spec.py to use pytest's caplog fixture instead of manually patching the logger.

This is part of a larger effort to modernize the test suite and improve log verification.

Changes:

• Removed patch.object(spec_module.logger, "exception").
• Added caplog fixture to the test method.
• Asserted that the exception message is captured in caplog.text.
