Fixes self-loop when generated implementation of an assisted factory method calls a generated component method with the same name.

Fixes self-loop when generated implementation of an assisted factory method calls a generated component method with the same name.

The problem exists in FastInit mode, where the private method name can conflict with the factory method name:

final class DaggerMyComponent implements MyComponent {
  @Override
  public FooFactory fooFactory() {
    return new FooFactory() {
      @Override
      public Foo foo() {
        return foo();  // This calls factory method rather than component method
      }
    };
  }

  private Foo foo() {
    return new Foo(getDep());
  }
}

The fix is to reference outer component when calling the private method within the anonymous class.
