Fix T97731: Python traceback no longer includes line-numbers

Regression caused by [0] that caused the error message to be
created based on a normalized exception (which hid line numbers).

PyC_ExceptionBuffer{_Simple} & BPy_errors_to_report
no longer clears the exception.

This could have been resolved by changing python_script_error_jump
however that would involve changes to reference counting that are more
risky (noted in code-comment).
