    Default gridpanel reconfigure fails when 'grouping' feature used on store w/ autoDestroy true

    Steps to reproduce (code snippet at end):
    • Create a gridpanel that uses "grouping" feature.
    • Attach a store that has autoDestroy===true.
    • Reconfigure the grid with a new store instance (can be identical to old, as long as it's a different instance).

    Exceptions generated
    First exception occurs within during grid refresh on the following line:
        return this.groupers.getCount() > 0;
    The problem is that groupers is null at this point. The exception is caught within XTemplateCompiler.applyOut but isn't handled in any way: i.e., the template application is simply aborted. Consequently, a second, unhandled exception occurs within Ext.view.Table.collectNodes on the line...
        this.all.fill(this.getNodeContainer().childNodes, this.all.startIndex);
    ...because the call to getNodeContainer() returns null (because the earlier exception prevented the view from being re-generated properly).

    Here's a simple app to reproduce... You should get the errors the first time you reconfigure the store by hitting the "Reconfigure..." button.
        requires: ['Ext.container.Viewport'],
        name: 'GridPanel Test',
        appFolder: 'app',
        statics: {
            storeCnt: 0
        launch: function() {
            var me = this,
                win = Ext.create('Ext.window.Window', {
                title: 'My Grid Window',
                layout: 'fit',
                floating: true,

                height: 400,
                items: [{
                    xtype: 'gridpanel',
                    title: 'Simpsons',
                    store: this.createStore(),
                    features: [{
                        ftype: 'grouping'
                    columns: [
                    { text: 'Name',  dataIndex: 'name' },
                    { text: 'Email', dataIndex: 'email', flex: 1 },
                    { text: 'Phone', dataIndex: 'phone' },
                    { text: 'Store Counter', dataIndex: 'storeCnt' }
                    height: 200,
                    width: 400
                fbar: [
                        text: 'Reconfigure store...',
                        handler: function() {
                            // Create a new store instance and reconfigure the grid with it.
                            // Note: The store's autoDestroy config ensures destruction of the old store
        createStore: function() {
            var storeCnt = ++this.statics().storeCnt;
            // Create a new store instance (albeit with same data...)
            return Ext.create('', {
                autoDestroy: true,
                fields:['name', 'email', 'phone', 'storeCnt'],
                { 'name': 'Lisa',  "email":"[email protected]",  "phone":"555-111-1224", storeCnt: storeCnt },
                { 'name': 'Bart',  "email":"[email protected]",  "phone":"555-222-1234", storeCnt: storeCnt },
                { 'name': 'Homer', "email":"[email protected]",  "phone":"555-222-1244", storeCnt: storeCnt },
                { 'name': 'Marge', "email":"[email protected]", "phone":"555-222-1254", storeCnt: storeCnt }
                proxy: {
                type: 'memory',
                reader: {
                    type: 'json',
                    root: 'items'
