Zackery Spytz 83df4e8ed6 [OCaml] Fix and re-enable the string_simple, minherit, and unions tests
copy_string() is a macro in the OCaml C API, so rename the function
to copy_str(). Add a runtime test.

The minherit runtime test was fixed by b64d685.

Use the proper syntax for accessing member variables in
