commit 55e1053ef693f2bfcb2eba3d8cc150e03dc4e811

    Correctly handle wired in unit IDs in -instantiated-with
    
    Summary:
    To handle wired in packages, we must rewrite all occurrences
    of unit ids like base-4.9.0.0 to base.  However, I forgot
    to do this on unit ids that occurred in unit identifiers
    passed via -instantiated-with.  This patch handles that case,
    plus a test.
