808: Shorten references

I'm noticing at least in Build 808 when I use ReSharper's quick fix to
shorten references, it shortens the references only to the level of the
current namespace. In other words, given this code where DoSomethingElse is
a static method:

namespace Foo.Bar
{
public class Test
{
public void DoSomething()
{
Foo.Bar.Blah.Class.DoSomethingElse();
}
}
}

I place the cursor on DoSomethingElse and use the quick fix, but it shortens
the reference to Blah.Class.DoSomethingElse() instead of
Class.DoSomethingElse(). Previous versions would shorten to
Class.DoSomethingElse() and add using Foo.Bar.Blah.
