scanner: Readd --warn-error to tests, fix test case

Commit b6fb70f9 wrongly disabled fatal warnings - in fact there
is a way to make this test case work, and it was a bug in the
scanner not processing virtual function annotations correctly.

Add a different test case for un-named parameters that doesn't
have a callback.
