List properties should be merged in reverse module dependency order

Module {
    name: "common"
    property stringList listProp
}
Module {
    name: "higher1"
    Depends { name: "common" }
    common.listProp: "higher1"
}
Module {
    name: "higher2"
    Depends { name: "higher1" }
    common.listProp: "higher2"
}

Product {
    name: "p"
    Depends { name: "higher2" }
    common.listProp: "product"
    property stringList showMeTheOrder: {
        console.info(common.listProp);
    }
}
