Richard Moe Gustavsen f9f1043e8a QVariant: guard usage of fromType.metaObject()
This patch amends 19874d6a63. That patch caused a
crash to occur when running the auto test
tst_QQuickApplicationWindow::attachedProperties().
The crash can be traced back to QMetaType trying
to access fromType.metaObject(), which is null.

This patch will add a guard to ensure that we
don't try to call a function on an object that is null.

Fixes: QTBUG-86517
