On the initial pass here I reached a faulty conclusion about what from the new world should shim into a NewInstanceInfo, based on a poor read of existing code. It actually _should've_ been based on an absolute instance after all, as evidenced by the expected result of TestContext2Refresh_targetedCount. Therefore the signature is changed here, and all of the callers (which, in retrospect, were all holding a full instance address anyway!) are updated to that new signature.
