Error in models/passing/InitializationErrorDetection.R

With revision 3958, I get an error in one model in the test suite, models/passing/InitializationErrorDetection.R , namely, "Error: An error was thrown with the wrong message: Observed argument is neither a data frame nor a matrix". Both of the first two omxCheckError() statements trigger it.

If this error reflects a real problem with our code, then of course the problem should be fixed. If not, then we just need to edit this test model so it doesn't fail.
