    Default 4.2.0beta : destroy tries to remove non-existing resizer handles

    Destroying a resizable component causes error when is has been initiated with custom handles config.

    Workaroud:
    Code:
    
    
    // BUG : trying to remove non-existing resizer handles
    Code:
    Ext.override(Ext.resizer.Resizer, {
            destroy: function() {
            var i = 0,
                exist,
                handles = this.handles,
                len = handles.length,
                positions = this.possiblePositions;
    
    
            for (; i < len; i++) {
                if(exist = this[positions[handles[i]]]) {exist.remove()};
            }
        }
        });
    Cheers,
