[Regression: 5.5 -> 5.6] PropertyChanges no longer properly restores binding on alias

// Test.qml
import QtQuick 2.0

Item {
    id: root

    property string myText: "hello world"

    ChangeTest {
        id: changeTest
        text: myText
    }

    states: State {
        name: "changed"
        PropertyChanges {
            target: changeTest
            text: ""
        }
    }

    MouseArea {
        anchors.fill: parent
        onClicked: {
            if (root.state == "")
                root.state = "changed"
            else {
                root.state = ""
                myText = "goodbye"
            }
        }
    }
}

//ChangeTest.qml
import QtQuick 2.0

Item {
    property alias text: myText.text

    Text {
        id: myText
    }
}
