Fix nullptr literal 0s which would look odd as nullptr

These all invoke the QFlags<>(Zero *) ctor, which is designed to
accept a 0, but no other int. But in doing so, it requires passing
a nullptr literal, and 0 is not a nullptr literal accepted under
-Wzero-as-null-pointer-constant or similar warnings.

Fix by using the QFlags::QFlags() ctor instead.
