55a7500343 [strong] Fix super in strong classes 
The functions of strong classes are born non extensible. But, when
the class is created we need to add an own private symbol representing
the [[HomeObject]] slot in the spec.

Like for the hidden_string property, we allow adding private own
symbols to non extensible objects.
