Remove wrong assert from QMetaType.

We can't assert that QMetaType helper arrays are initialized. In rare
situations it may happen that QMetaType compiled without support for an
external type (without compiled Gui or Widgets libraries) will be asked
for additional information for the type.

For example (assuming Qt is compiled with --no-gui):
// typeId it may be received over network (QMetaType::QImage)
void *ptr = QMetaType::create(typeId);
