Fix the unresolved types if used as ignored type-alias arguments

Mockito tries to keep function type aliases unrolled if possible,
so for example, for the code

```dart
typedef Ignore<T> = String Function();
abstract class C {
  void m(Ignore<SomeClass> c);
}
```

the generated mock will have this override:
```dart
  void m(_i1.Ignore<SomeClass>? c) => /* ... */;
```

But the way `TypeVisitor` collects potentially used types, excludes
ignored type alias arguments (non-ignored ones are visited while
visiting the right hand side of the `typedef`).

Make sure we visit all type alias arguments unconditionally.
