Nulling of sequences in C++ isn't working.

Currently the following is passing:

BOOST_AUTO_TEST_CASE( Sequences )
{
  Fixture f;
  ImageIPtr img = new ImageI();
  BOOST_CHECK( img->annotationsLoaded );
  img->annotations.push_back((ImageAnnotationPtr)0);
  img->unload();
  BOOST_CHECK( !img->annotationsLoaded );
  img->annotations.push_back((ImageAnnotationPtr)0); // TODO This should fail with NPE!
}

This may be best taken care of by using Ice's protected? metadata.

Added failing test in r2215

Fixed with #1106 - now using protected as of OmeroBlitz migration.
