Title: Added specs for Struct#instance_variables behavior

In working on the last patch I submitted I realized there was no coverage of the Struct#instance_variables behavior. Even though there are ivars backing the struct attributes they are not present in the return of Struct#instance_variables. This spec verifies that behavior.
