"Get-InstalledModule" and "Uninstall-Module" errors do not set $? to $false

[o-l-a-v]

This is using the latest stable version "1.4.6" of "PackageManagement" as of 2020-02-26 on Windows PowerShell 5.1

I've found that when errors happen in "Get-InstalledModule" and "Uninstall-Module" commands, errors is not added to $Error variable, and $? is not set to false unless $ErrorActionPreference is set to 'Stop'. Also, reading the error messages, I see that reported commandlet ran according to the error messages added to the terminal, are "PackageManagement\Uninstall-Package" for "Uninstall-Module" and "PackageManagement\Get-Package" for "Get-InstalledModule". When using these commands, $? is righfully set to $false if they fail, but these commands are not adding error to $Error either.

Code to reproduce (designed to run line per line)

# Settings
## PowerShell Preferences
$ErrorActionPreference = 'Continue' # Default for new PowerShell session



# PackageManagement
## Import
Import-Module -Name 'PackageManagement' -Force

## Output imported version of the module
$(Get-Module -Name 'PackageManagement').'Version'.ToString()



# Assets
## Fictive module
$Name = 'SomeModuleName'
$Version = '1.2.3'



# Get
## Using "Get-InstalledModule"
Get-InstalledModule -Name $Name -RequiredVersion $Version
$?
$Error[0]

## Using "PackageManagement\Get-Package"
PackageManagement\Get-Package -Name $Name -RequiredVersion $Version
$?
$Error[0]



# Uninstall
## Using "Uninstall-Module"
Uninstall-Module -Name $Name -RequiredVersion $Version
$?
$Error[0]

## Using "PackageManagement\Uninstall-Package"
PackageManagement\Uninstall-Package -Name $Name -RequiredVersion $Version
$?
$Error[0]

Output showing wrong cmdlet is reported in the error + $? is not set correctly.

This all works for the "Find-Package" command.
