  Fix comparison for classes implementing __eq__.

There are currently only two new failing tests:

* Comparing an object with a proxy of the object fails (but comparing the proxy with the object is fine!)
* Comparing a proxy with itself fails

But these tests run fine when deleting the `__eq__` method on the `Something` class which is the class of `self.x`.

  Unwrap other if it is a proxy, so the proxy can compare equal to itself.
