OX-02 P14: prove the extension loaded from its own trace, not the module list

The run on a28c958 (MEF cache rebuilt) shows Owen.VisualStudio composed in the IDE
and working: its trace has 'Owen live analysis loaded', a workspace snapshot with
the unsaved Use.cs and Roslyn's in-memory generated documents, and publication 1 of
the project with no entries (K1). Only the driver's check was wrong: a .NET Framework
assembly is not reliably among Process.Modules.
