"Test VSTi" in instrument-window - what is this?

[posssu]

In every project when I hit APPLE-SHIFT-T and open the library-list (Notion 2 instruments, Notion 3 instrument, Garritan Personal Orchestra...), there's also an entry called Test VSTi.

Is this some debugging instrument that made its way into the demo-version that I had and now it's left in the full version? If it's not a feature of Notion 3, how to make it disappear?
