Image field not saving files permanently

Problem/Motivation

Images are not saved permanently when updating configuration. The logo will disappear after a cron run or site rebuild.

Steps to reproduce

1. Upload an image to the Login service logo
2. Save the file
3. Once cron runs or temporary files are deleted, notice that the image is not displayed or saved in configuration

Proposed resolution

The configuration form does not have the proper calls to save the file permanently. Make sure there are "()" next to these lines:

   $file->setPermanent();
   $file->save();
