* Cross target Octokit.Tests against netcoreapp1.0 and net452
* Add net45-specific references
This fixes a build error after adding the net452 target:
error CS0656: Missing compiler required member 'Microsoft.CSharp.RuntimeBinder.CSharpArgumentInfo.Create'
* Add SimpleJson conditional compilation symbols for net45
* Disable AppDomain when running tests

* Use nameof operator instead of magic strings
* Remove conditional compilation symbols as they are not used in the conventions tests project
* Enable cross targetting in the conventions tests project
* Run tests against netcoreapp1.0 only when not on Windows
* Going too fast bites you
