Error writing QVariant(QList<SubClassA*> ) inside property QList<ClassA*>

Until Qt5.5.1 i was writing to a qproperty a list of a subclass using QMetaProperty::write()

Now in 5.6 i have to convert QList<SubClassA*> to QList<ClassA*> to be able to write it successfully.

Note that SubClassA inherit ClassA
