Doc: some ComboBox functions must be used after component completion

The internal QQmlDelegate model may not be ready until after
componentComplete() is called. For example, the following code will
print -1 for the find call, even though printing the model will
show the "Hello" entry:

    ComboBox {
        id: comboBug
        anchors.centerIn: parent
        model: ["123", "BlaBla", "Hello", "Turtle"]
        currentIndex: {
            console.log("Model: " + comboBug.model)
            console.log("Find:  " + comboBug.find("Hello"))
            return comboBug.find("Hello")
        }
    }
