Subject: Replace set union_update() references with update()

Replace set union_update() references with update()

The autogenerate api references the `union_update()` method of sets which was removed in Python 2.4. The previous method is actually an alias for the `update()` method.

This PR replaces the api reference with the correct one for Python 2.7
