iOS .imageAsResized() on image/jpeg generates a blob with mimeType image/png

On iOS .imageAsResized() on image/jpeg generates a blob with mimeType image/png


```
blob = ImageFactory.compress(blob, 0.8, ImageFactory.JPEG);

// now blob has mimeType image/jpeg

blob = ImageFactory.imageAsResized(blob, { width: 1000, height: 1000, quality: 0.8 }, ImageFactory.JPEG);

// now blob has mimeType image/png

```

P.S. The third parameter on iOS is not supported yet
