Marble -touch or any other custom application, which uses
MarbleDeclarativeWidget does not save center position and zoom of the map when
you close the application.



Reproducible: Always

Steps to Reproduce:
1. Create standart QML application
2. change text in the main QML to follow:
/////////////////// main.qml //////////////////////////////////
import QtQuick 1.1
import org.kde.edu.marble 0.11
Rectangle {
    id: widget
    width: 500
    height: 700

    MarbleWidget {
        id: map
        anchors.fill: parent
        MarbleSettings{
            id: settings
        }
        workOffline: settings.workOffline
        mapThemeId: settings.mapTheme
        radius: settings.quitRadius
        projection: settings.projection
        activeFloatItems: [ "compass", "scalebar", "progress" ]
        activeRenderPlugins: settings.activeRenderPlugins
        Component.onCompleted: {
            // Load last center of the map.
            center.longitude = settings.quitLongitude
            center.latitude = settings.quitLatitude
            tracking.lastKnownPosition.longitude = settings.lastKnownLongitude
            tracking.lastKnownPosition.latitude = settings.lastKnownLatitude
            initialized = true
        }
        Component.onDestruction: {
            settings.quitRadius = radius
            settings.quitLongitude = center.longitude
            settings.quitLatitude = center.latitude
        }
    }
}
////////////// END //////////////////////

3. Scroll the map and change zoom
4. Close the application
5. Run the application again
Actual Results:  
The Map starts with (0, 0) center position  coordinates and with minimum zoom

Expected Results:  
The Map starts with center position and zoom, which it has when the application
was closed.

I think, that the reason of this bug in MarbleSettings.qml
In my application the signal "onDestruction" from MarbleSettings.qml is emitted
earlier, than "onDestruction" on MarbleWidget in main.qml
