The whole class does not get parsed if END METHOD. is used at the end of a constructor

[gustason]

For example,

CLASS DecoratedMotorcycle: 

    CONSTRUCTOR DecoratedMotorcycle():
        message "moto".
    END METHOD.

END CLASS.

END METHOD should not be used to end constructor. It should be END [CONSTRUCTOR]

@gustason please check and close the issue if everything is okay.

Even though this is not written in the documentation, it does compile. It should not be used, however, it is possible to use it anyway. Therefore, it should be parsed by tree-sitter.
