Features importance helper issue

[khalidamer]

Describe the bug if a UnicodeEncodeError is raised when calling decode_str_or_unicode(), the variable fname will not be defined, and an UnboundLocalError will be raised when trying to append it to the decoded_feature_names list.

To Reproduce Steps to reproduce the behavior: Call 'twml/twml/contrib/feature_importances/helpers.py' ' _get_feature_name_from_config' function, with feature name contains characters that cannot be decoded using the default encoding, a UnicodeEncodeError will be raised when calling decode_str_or_unicode(). The function logs this error but does not handle it otherwise, so the feature name variable will not be defined and will raise error in appending step.
