[Serializer] Fatal error in denormalizeObject for Normalizers that do not implement DenormalizerInterface

If there is a list of Normalizers, and only some of them implement DenormalizerInterface, then a call to deserialize() can result in a fatal error.

This is because denormalizeObject does not check that the Normalizer implements DenormalizerInterface before calling supportsDenormalization on it.

Previously the HelperSet class was only tested by way of the Application testcase. This patch adds a dedicated testcase and increases test coverage of the class to 100%.
