fix unused arguments warnings

Fix deprecation warning of qMetaTypeId(T *)

See merge request !46

Since Qt-5.1, the version with an argument is deprecated
```
template <typename T>
QT_DEPRECATED inline Q_DECL_CONSTEXPR int qMetaTypeId(T *)
{ return qMetaTypeId<T>(); }
```

So use `qMetaTypeId<T>()` without argument.
