Broken paste image

[pludov]

When pasting an image in the editor:

• The editor closes just after the name is entered
• The markdown file is updated with an incorrect link : [uploading...](blob:http://cloudnext-srv:1080/65181c9a-8ac9-4e3c-8182-2527ea0fb7d0)
• An image file is created where expected, but with dummy content:

root@bebb8ef7a834:/var/www/html/data/admin/files/Documents# cat capture.png 
[object ArrayBuffer]

The browser's query inspector shows that two call PUT savefile are done, the first with the [uploading...] link, the second with the updated link. The second fails (400), with an error stating the file has been modified elsewhere. Both requests send the same mtime value.
