Warning: Dependency specified was Microsoft.AspNetCore.Diagnostics.Elm but ended up with Microsoft.AspNetCore.Diagnostics.Elm 0.1.0

C:\Users\mharder\.dotnet\x64\sdk\2.0.0-preview2-006127\NuGet.targets(98,5): Dependency specified was Microsoft.AspNetCore.Diagnostics.Elm  but ended up with Microsoft.AspNetCore.Diagnostics.Elm 0.1.0. [D:\Git\Entropy\.build\KoreBuild.proj]

Root cause is that AspNetCoreLabsVersion was incorrectly removed from dependencies.props in #217, but the property is still used by samples/Logging.Elm/Logging.Elm.csproj:

<PackageReference Include="Microsoft.AspNetCore.Diagnostics.Elm" Version="$(AspNetCoreLabsVersion)" />
