ngCropper on load new image -> not working

[djpysu]

When I try to upload a second image, it's not working - the cropper remains with the first image.

@djpysu I found a solution on the #22

I changed the method onFile and solved.
See:

$scope.onFile = function (blob) {
        Cropper.encode((file = blob)).then(function (dataUrl) {
            $scope.dataUrl = dataUrl;
            $timeout(hideCropper);
            $timeout(showCropper);  // wait for $digest to set image's src
        });
    };
