Title: Hotfix for #3289 `ReflectionParameter#getClass()` on `callable` type hint should not raise exceptions

See #3289 - `ReflectionParameter#getClass()` on `callable` type hint should not raise exceptions

PR is NOT tested as I didn't have time to build HHVM today, so I'll have to trust travis here.
