Cleanup of the release pipeline: removed a task that didn't work and …

…a switch in Nuget Pack that wasn't used (#333)

* While testing csproj PR, saw a couple places that could be cleaned up in release pipeline.  Removed copy task and the $(BuildConfiguration) to the nuget pack task

* Remove debug statements the disabled push to nuget and garnet release.  All should work now when ran.
