patch 9.0.1883: Vim9: Calling an interface method using a child object fails
Problem: Vim9: Calling an interface method using a child object fails
Solution: Search methods of parent class
When a class implementing an interface is extended by another class and
a child class instance is passed to a function that accepts the
interface, calling an interface method doesn't work properly.
closes: #13053
