Incorrect using of attribute in test

[Sergey Kraynev]

Functions Fn::GetAtt and get_attr need for getting resource attribute according to attribute_schema.
Resource generic_rsrc.ResourceWithComplexAttributes is used in test test_hot.StackGetAttrValidationTest.test_validate_props_from_attrs, this resource does not have attribute flat_map and string, so I offer change type of resource1 on generic_rsrc.ResWithComplexPropsAndAttrs.
