[erl] fix generator to use unexpanded structs for reply_types on functions

This fixes a bug where thrift_client would return a tuple rather than a tagged record when the called function returned a struct.

Test plan:
  in tutorial client:
    Log: {sharedStruct,1,<<"RARG">>}
  instead of:
    Log: {1,<<"RARG">>}
