    Return 400 if registry returns 400.

    Fixes bug 919244. The registry would return 400 for invalid input,
    which resulted in an exception.Invalid being thrown in the registry
    client. There was no exception handler for this exception, so it
    got bubbled up and turned into a 500. This should fix the problem
    by adding the missing exception handlers.
