Save-PSResource & Install-PSResource do not include empty files & folders

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.

Steps to reproduce

Tested against a fileshare based repository

Empty folders and empty files - and empty folders containing nothing but empty files - are not installed / deployed.
Manually unwrapping the .nupkg files proves they were correctly included in the publishing and only go AWOL on install/deployment.

If a module is then built on a template that also includes empty folders, where files within are dynamically included at import (if any), and published, it will generate an error in import, as it tries to enumerate a folder that does not exist.

Expected behavior

Install-Module ContosoTools -Repository local
Import-Module ContosoTools
#-> No errors

Actual behavior

Install-Module ContosoTools -Repository local
Import-Module ContosoTools
# Error: Get-ChildItem: Cannot find path '<documents>\PowerShell\Modules\ContosoTools\1.0.0\internal\'

Reproduce the issue with a fileshare repository using Save-PSResource and Install-PSResource, then verify the published .nupkg contents against the installed module. Trace the install or deployment path for empty files and folders. Done means empty folders and files survive installation and Import-Module ContosoTools no longer reports a missing internal path.
