[api] Add CHANGELOGs for API caching changes
Use a more sensible method to get log entry partial name
When removing defunct zone members use classify instead of capitalize when deleting zone members by zonable_type.

When creating a custom zone member type like zip_code for example using capitalize removes all models with zonable type != Spree::Zip_code instead of Spree::ZipCode
