[FIR2IR] Properly handle intersection types in interface delegation

The changes to the irText test data result in the fact that we
now unconditionally unwrap substitution overrides of delegation targets
whereas before we built an unsubstituted scope of the type we delegate
to. If we delegate to a class A : B<C>, the unsubstituted scope of
A can still contain substitution overrides for inherited generic methods
from B<T> that we didn't unwrap before but do unwrap now.
