DATAMONGO-901 - Fixed regression of not registering type predicting post processor.

The changes for DATAMONGO-843 introduced a regression by skipping the registration of the RepositoryInterfaceAwareBeanPostProcessor. This can cause the wiring of repository bean definitions to fail depending on in which order the bean definitions get instantiated.

This change reintroduces the registration and adds an explicit test case for it.
