Replace QList<Person*> with QVector<Person*> and function pointers

The usage of the QQmlListProperty QList constructor is discouraged since
QList violates QML's memory management rules.
Replaced the QList with a QVector and passed the function pointers to the
QQmlListProperty constructor instead, as officially recommended.
