Return nil if class constant cannot be found

[WesleyW]

When mocking controllers in Rspec, the class may be constructed in code, which means a class may look like #<Class:0x000000015ea185d8>, causing Object.const_source_location to fail. These should just return nil

@WesleyW This looks fine, but is there a way to detect these anonymous classes and return nil explicitly rather than just rescue NameError?

[WesleyW]

@alexevanczuk I don't think so... After fiddling around a bit more, I think it's just specs not always conforming to sorbet types. I can repro my original issue by calling CodeOwnership.for_class(Class.new.new.class), but this fails the typecheck here, since klass is an anonymass class instead of a Class.
