Package installation fails on UWP

[nblumhardt]

Because of the absence of System.Threading.Thread on UWP (despite its .NET Standard 1.4 designation) the sink package cannot be installed:

Restoring NuGet packages... 
To prevent NuGet from restoring packages during build, open the Visual Studio Options dialog, click on the Package Manager node and uncheck 'Allow NuGet to download missing packages during build.'
System.Threading.Thread 4.0.0 provides a compile-time reference assembly for System.Threading.Thread on UAP,Version=v10.0, but there is no run-time assembly compatible with win10-x64.
One or more packages are incompatible with UAP,Version=v10.0 (win10-x64).
NuGet package restore failed.

Even though the package supports .NET Standard 1.1, the tooling won't fall back to it here. The only short-term possibility is to remove the dependency, which can be achieved by updating to the latest PortableTimer implementation from the upstream PeriodicBatchingSink.

As a workaround for Windows you could add netcore45(least windows tfm for uwp platforms) into the frameworks section:

"netcore45": {
    "frameworkAssemblies": {
      "System.Net.Http": { "type": "build" },
      "System.Net.Primitives": { "type": "build" },
      "System.IO": { "type": "build" },
      "System.Threading.Tasks": { "type": "build" },
      "System.Text.Encoding": { "type": "build" }
    }
 },

Then UWP project would choose this as more specific target than netstandard1.3 (because netcore45 describes set of uwp platforms, not contracts like netstandard1.x).
Taking dev dependency from PBS into the master here probably was not the best option

Thanks - good suggestion, I should have thought of that 👍
