    Fix tests on Python3.10

    Both test_property_protection_with_missing_operation and
    test_property_protection_with_misspelt_operation rely on a bug in Python
    3.9: the "]" character in a section name is not read, so section
    '^[0-9]' is read as '^[0-9'. This causes _compile_rule to fail and raise
    the exception the tests are expecting.

    In Python 3.10, this bug has been fixed and the exception is no longer
    raised. Instead, CONFIG.get() raises a NoOptionError in _load_rules,
    which is not caught.
