Build error when one test project references another, redux

[vikukush]

Describe the bug

I have the same exact issue as in #3813, it is not solved for me by the PR, because my test assemblies use InternalsVisibleTo, so they can see autogenerated Internal classes, so they still get the conflict:

D:\dbs\sh\l23t\1010_175302_0\cmd\7\Test\UnitTests\BIAndReporting\Reports.Shared\obj\Debug\net48\TestPlatformEntryPoint.cs(13,9): warning CS0436: The type 'SelfRegisteredExtensions' in 'D:\dbs\sh\l23t\1010_175302_0\cmd\7\Test\UnitTests\BIAndReporting\Reports.Shared\obj\Debug\net48\AutoRegisteredExtensions.cs' conflicts with the imported type 'SelfRegisteredExtensions' in 'MS.Dynamics.Test.BIAndReporting.Common.UnitTests, Version=7.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. Using the type defined in 'D:\dbs\sh\l23t\1010_175302_0\cmd\7\Test\UnitTests\BIAndReporting\Reports.Shared\obj\Debug\net48\AutoRegisteredExtensions.cs'. [D:\dbs\sh\l23t\1010_175302_0\cmd\7\Test\UnitTests\BIAndReporting\Reports.Shared\Shared.UnitTests.csproj::TargetFramework=net48]

Steps To Reproduce

[assembly: InternalsVisibleTo("MS.Dynamics.Test.BIAndReporting.RunTime.UnitTests, PublicKey=blah")]
