Specify recursive_guard as kwarg in FutureRef._evaluate

In CPython 3.12.4/3.13, the function signature of `FutureRef._evaluate`
changed such that `recursive_guard` is no longer a positional argument;
it is now keyword only [0][1].

To accomodate this, specify `recursive_guard` as a kwarg. This syntax is
backwards compatible with earlier versions of the function signature.
