Adapt to renamed properties by using MappedProperties in association deserialization.

Revert the changes that employed manual annotation lookup as that would cause invalid associations of fields and accessor methods for properties shadow renamed. Instead, we now use MappedProperties that already contains a mapping between the Jackson field names and Sprign Data property names.

Fixes: #2165
