LPS-33400

Hey Brian,

In LPS-33320, we made Activity Interpreters backward compatible, but the local service is not.

I know you mentioned you kinda wanted it to break if the interpreter is being called wrong.  However, in the Open Social portlet - LiferayActivityService.java, it doesn't seem like we can create the serviceContext.

Feels like a lot of duplicated code, but might be the best way to fix this for now.  Let me know if we should be doing something different.  Thanks.
