Uploading multiple images with same name doesn't add the metadata stats correctly

[bfintal]

To reproduce, you need 2 files:

1. IMG_001.webp (this was already optimized into WebP)
2. IMG_001.jpg (a different image, but with the same name and a jpg)

Perform the following:

1. Create an image block and select "Media Library" to upload an image
2. Highlight the 2 files above and drag them into the media library
3. See that the 2 images were uploaded, but the IMG_001.jpg that was converted into .webp does not have the optimization stats
