Public bug reported:

With older Qt versions, we use private APIs (QQmlValueType and friends)
for exposing value types, and managed to make it work so that when
OxideQSslCertificate::issuer() returns a null QVariant, the value is
converted to null in Qml.

However, with the built-in gadget support in Qt5.5, this is no longer
working and behaving inconsistently between 2 APIs:

- When OxideQSecurityStatus::certificate() returns a null QVariant, the value gets converted to null in Qml.
- When OxideQSslCertificate::issuer() returns a null QVariant, the value gets converted to an object in Qml (verified with typeof), and calling toString() on the object gives "QVariant(QVariant): undefined".

Both APIs return a null QVariant with a type of QMetaType::VoidStar
