Install fails when manifest references Data with ConvertFrom-StringData

Steps to reproduce

When trying to install modules from a fileshare repository with ConvertFrom-StringData in the manifest with current prelease of PSResourceGet (1.1.0 rc3), generate an error:

Install-PSResource: The command 'ConvertFrom-StringData' is not allowed in restricted language mode or a Data section.

Getting it from the PS Gallery works fine.

I will give an example using the PackageManagement module for demonstration purposes, but othe modules show the same problem, such as PlatyPS.

Expected behavior

Import-Module Microsoft.PowerShell.PSResourceGet
Register-PSResourceRepository -Name 'My-PSGallery' -Uri \\path\to\file\share -Trusted -Priority 1
Save-PSResource -Name PackageManagement -Repository PSGallery -TrustRepository -AsNupkg -Path \\path\to\file\share
Install-PSResource -Name PackageManagement -Repository My-PSGallery

This should process just fine and make it possible to import the module to use it.

Actual behavior

Install-PSResource -Name PackageManagement -Repository My-PSGallery

Will return:
```PowerShell
Install-PSResource: The command 'ConvertFrom-StringData' is not allowed in restricted language mode or a Data section.
Install-PSResource: Package(s) 'PackageManagement' could not be installed from repository 'My-PSGallery'.

Added info: Current PackageManagement module version used for the issue is 1.4.8.1

This seems to be a recurring problem with PSResourceGet 1.1.0 (and PowerShellGet 3.0.23-beta23) as I'm also seeing an unexplained "ConvertFrom_StringData" error with Find-PSResource pointed at a filesystem nuget repo.

If, instead, I Import PowerShellGet version 2.2.5, and do a Find-Module MyModule -Repository MyFileRepo it finds the module just fine.
