* Bug fixes
* Nitpick
* -Fixed failed tests
-Added test to cover trx logger scenario.
* Fix for issue https://github.com/Microsoft/vstest/issues/241
* Fix for failed test. We have taken fix where dotnet test will return nonzero if test fails. In multi TFM scenario if test fails it termates the whole process as dotnet test is returning 1. As a fix of this we should continue if some test fails for next TFM
* Bump Microsoft.Testplatform.CLI and Microsoft.NET.Test.Sdk version
2) Added test to address above change
3) Crossgen were creating problem for full CLR built assemblies. Removed All those assembly from Crossgen list.
4) Removed the line of code which were deleting Extensions folder under sdk folder as this folder contain trx logger dlls
