spurious errors for team with constructor with declared lifting

[stephan]

Given this code example:

public team class SuperFoo {
    public class Role {}
    public SuperFoo(Role r) { }
}

public team class Foo extends SuperFoo {
    public class Role playedBy String {}
    public Foo(String as Role r) { 
        super(r);
    }
}

the real compiler finds no error but the CompilationUnitProblemFinder does, resulting in a "small" error marker in the gutter, saying (at position 0):

The constructor SuperFoo() is undefined
