Save-PSResource & Install-PSResource do not include empty files & folders #1819

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\'
