operator<< used the wrong criterium for deciding whether the data is stored as atomic_cell or collection_mutation, resulting in catastrophical failure if it was used with frozen collections or UDTs. Since frozen collections and UDTs are stored as atomic_cell, not collection_mutation, the correct criterium is not is_collection(), but is_multi_cell(). Closes #8134
