#16458: image_resize() treats all resized images resulting in JPEG as having the
.jpg extension

 Steps to reproduce:
 1. Upload foobar.jpg
 2. Upload foobar.jpeg
 3. WordPress will use foobar-200x200.jpg and such for the intermediate
 sizes of the second image

 `wp_handle_upload()` uses `image_resize()` which attempts to convert all
 images except GIFs/PNGs to JPEG and hardcodes the .jpg extension. This may
 well affect all image types handled by GD aside from GIF/PNG when
 WordPress is given the correct settings to handle them.

 The real issue for me is that if the resize procedure fails, it does so
 silently and just passes back the URL for an existing file matching the
 output filename.
