some imports are invalid when run standalone, causing manually triggered refactor of awscli credentials to fail.

Required to fix in case this functionality used to generate standalone profiles.json in ~/.stsaval for applications where awscli cannot, or is not, configured.

Traceback (most recent call last):
  File "stsAval/refactor.py", line 16, in <module>
    from stsAval import logd
ModuleNotFoundError: No module named 'stsAval'
