dnvm use alias doesn't work when alias points to coreclr

[victorhurdugaci]

Even though the alias points to coreclr, when I run kvm use <alias> it tries to use the clr runtime

D:\aspnet\dnx>dnvm upgrade -r coreclr -amd64

As described in #214, this is because aliases seem to be ignoring the runtime type.
