[Work Item] SetupAssist Fully Test out Virtual Directories in a lab and commit changes

Describe the work
Need to go fully through a lab and remove the virtual directories from AD, then run SetupAssist and have it clean up the IIS applicationHost.config to be able to run New-VirtualDirectory again on the server afterwards. Also provide that as a action item in the results.

Then go through the same steps with messing up the IIS settings in some way then determine if we should be adding settings back (likely hard to do) or just removing it as before in the script regardless of the state of AD. It would be nice to add them back if AD exists, otherwise, provide an action plan for how to address the issue and make sure New-VirtualDirectory does work.

Also include pester testing for these scenarios.
