Sunyeop Lee e328db38c0 Fix git_review.cmd.CommandFailed: <exception str() failed>
Neither the CommandFailed nor ChangeSetException classes have
docstrings, so self.__doc__ is initialized to None and can't be
trivially combined with other strings (nor would there be any point
in doing so). Just drop these unnecessary references.
