Fix crash when using signal handlers on group properties

This is a regression introduced with commmit
49a11e882059ee1729f776722e085dd21d378c36: The typeRef can be null.

I found this when testing grouped properties and property revisions.

<TestComponent.qml>
import QtQuick 2.0

Item {
    property alias textEdit: textEdit

    TextEdit {
        id: textEdit
    }
}

import QtQuick 2.8

Item {
    TestComponent {
        textEdit.onEditingFinished: console.log("test")
    }
}

Instead of an error message, this crashes without this patch.
This is a regression introduced by using QQmlType by value.
