Can't install System.Management.Automation from NuGet/MyGet: NU3008: The package integrity check failed

[Dennis-Petrov]

Greetings.
Can't install System.Management.Automation 6.0.4 both from MyGet and NuGet package sources.

Steps to reproduce:

0. Ensure, that System.Management.Automation is not in local package cache.
1. Create new .NET Core 2.1 Class Library project. I'm using VS 2017 15.8.2.
2. Open "Manage Packages for Solution" tab, and select required package source (either default NuGet or https://powershell.myget.org/F/powershell-core/api/v3/index.json).
3. Browse for System.Management.Automation.
4. Check project and click Install.
5. Install will fail with "NU3008: The package integrity check failed". It doesn't matter, which package source was selected.
