why is run_one_last_time set to False if callback_by_exception is defined

[laur89]

See https://github.com/pnpnpn/retry-decorator/blob/master/retry_decorator/retry_decorator.py#L34:
when callback_by_exception is defined and in effect, then run_one_last_time is defaulted to False.

1. why is it so?
2. what's the purpose of run_one_last_time to begin with? To be able to swallow exceptions by the retry logic?

In any case, run_one_last_time should always default to True.
