[Python] Equality between Records with None fields fails

[HLWeil]

Description

Equation between two Records fails in python, when the Record Type contains an Option field and the value bound to this field is None. The error message is the following:

TypeError: '<' not supported between instances of 'NoneType' and 'NoneType'

Repro code

[Please provide the F# code to reproduce the problem or a link to the REPL.
Ideally, it should be possible to easily turn this code into a unit test.](https://fable.io/repl/#?code=MQJwBARAdgrg5gUwC4C4wDECGAjANggOgGEB7EBAGjABYCAmAgBggFgAodkgBwSgx3zEyCTjz4BlAJ4BnJAgC2Q3PgDGSAJYko0ggHFeCEOpXtRvMFNkKCAFQQAPJAQBKCODFyYQAUXtdy0tKa2qZsSJI8YK4qYAC87GCJYADeCUnpAIJgaLJGUHBg3BpaaYkAvqH4SGCYcSlZsWAAcloIFWxVYNh1yQ3Nre3s-upQSABmfBAApNgQYAAUtY3YAJTsQA&html=Q&css=Q)

Reason

The failing function is the following:

def record_compare_to(self: Record, other: Record) -> int:
    if self is other:
        return 0

    elif hasattr(self, "__dict__") and self.__dict__:
        for name in self.__dict__.keys():
            if self.__dict__[name] < other.__dict__.get(name):
                return -1
            elif self.__dict__[name] > other.__dict__.get(name):
                return 1

    elif hasattr(self, "__slots__") and self.__slots__:
        for name in self.__slots__:
            if getattr(self, name) < getattr(other, name):
                return -1
            elif getattr(self, name) > getattr(other, name):
                return 1

    return 0

This is fixed by #3606

It will be included in the next Fable release.
