Crashing trying to get INDIRECT_get_classes_properties() of entities with Inverse relations

[carolreis]

Error:

    if   r.property._class_property_some and ((r.type == VALUE) or (r.type == SOME) or ((r.type == EXACTLY) and r.cardinality >= 1) or ((r.type == MIN) and r.cardinality >= 1)):
AttributeError: 'Inverse' object has no attribute '_class_property_some'

The following code doesn't treat the case of Inverse property, which has no _class_property_some nor _class_property_only property.

def INDIRECT_get_class_properties(Class):
    l = set()
    for r in _inherited_properties_value_restrictions(Class, None, set()):
      if   r.property._class_property_some and ((r.type == VALUE) or (r.type == SOME) or ((r.type == EXACTLY) and r.cardinality >= 1) or ((r.type == MIN) and r.cardinality >= 1)):
        l.add(r.property)
      elif r.property._class_property_only and  (r.type == ONLY):
        l.add(r.property)
        
    for storid in Class.namespace.world._get_triples_s_p(Class.storid):
      Prop = Class.namespace.world._get_by_storid(storid)
      if not Prop is None: # None is is-a,...
        l.add(Prop)
    return l
