Fix public key token.

[StephenBonikowsky]

• Arcade infrastructure set the default value to 'MicrosoftShared' which resulted in token 31BF3856AD364E35
• It should have been set to 'Microsoft' for token b03f5f7f11d50a3a

fixes #3787

Getting some really strange check failures, going to close and re-open.

Ignoring all the "dotnet-wcf-ci-clone" checks, everything looks good now.

I'm going to merge so that I can build packages and have the vendors validate before we provide them for release.

@StephenBonikowsky After this change I found strange behavior, when my project is referenced to 4.6.0-preview8.final version of system.servicemodel.primitives. I got error: Could not load file or assembly 'System.ServiceModel.Primitives, Version=4.6.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. . Output folder contains system.servicemodel.primitives.dll with PublicKeyToken=b03f5f7f11d50a3a
This files
system.servicemodel.primitives\4.6.0-preview8.final\lib\net461\System.ServiceModel.Primitives.dll
system.servicemodel.primitives\4.6.0-preview8.final\ref\net461\System.ServiceModel.Primitives.dll
now have different publickKeyToken.
I'm not sure, but It seems that this leads to the fact that the msbuild puts a ref to one version of the library(31bf3856ad364e35), and copies another(b03f5f7f11d50a3a).

@botinko thank you for reporting this, I will look into it and see what is going on.
