Rafael Guterres Jeffman f53ca3ad39 pylint: Ignore usage of 'unicode' before assignment 
New versions of pylint ignore Python 2 functions and types, evaluating
'unicode' as "undefined". ansible-freeipa will always define 'unicode'
when running under Python 3, and it is always defined under Python 2.

This patch fixes these false positives.
