@ViewsArgument("argument_comment_user_uid") - Need testing

Problem/Motivation

While reading the code - This stuck out like a sore thumb. . and thought it was worth fixing.

UserUid - already uses a create method, so it is a small thing to
convert a \Drupal::config() call into using a config factory service call.

Steps to reproduce

Proposed resolution

Pass in configFactory parameter to UserUid
