NullReferenceException in RuntimeEnvironmentHelper under .NET 4.5 using Logging

[adamhathcock]

I wrote this under DNX but maybe it's more appropriate here: aspnet/dnx#3218

Basically, the usage of a DNX specific thing causes an exception when trying to use Console logging. I have a sample and more details on the other issue.

Yep, it's a bug. It should be resolved in RC2.
