Initialize logger if no log_dir is configured during log purge

[craigkai]

The logger can end up not being _configured if this is not called. This can occure when log level is set to a stricter level like error and no errors occur, then when we call the purge_logs function our handler could be un-configured and not have a log_dir attribute -- resulting in the function bailing out.

Hi @craigkai !

Sorry for the late reply, but we were really busy with the new release process.

How do you feel about adding a test that exercises this issue so we can ensure that does not happen again in the future?

I'll see what I can do!
