HONEYCOMB-331: unify initialization handling

Due to incorrect instance of check, InitSubtreeReader was never created
in CompositeReaderRegistryBuilder.getSubtreeHandler().

As a consequence, initializers registered by subtreeAdd*, were not invoked.

The patch:
- fixes mentioned check,
- makes readers implement InitReader instead of directly
  implementing Initializer
- includes missing unit tests for GenericReaders.
