Record is reset on attachment upload

[gignonje]

For now, if you fill the form and then upload your file, the form is reset after the file upload, erasing all you have written.

Bug reproduction scenario:

• Click the add button (+) on the bottom of the page
• Fill the form
• Click browse on the page that open and choose the file you want to upload, then click "Déposer"
• Your file has been uploaded and the page reloaded, but your form is now reset and you have to write everything again

Bug reproduction scenario:
-click the (+) button at the bottom of the page to deposit
-Fill the form that appears (name, title...)
-Click on "choisir un fichier" and choose the file you want to upload, then click on "déposer" to deposit it
-A page of confirmation appears to notifies that the file has been successful uploaded. However, the form disappeared and you have to go on the previous page to fill it again.

Problem:
with the two scenarios below, after the succes or error of the upload, the edit page does not reloaded. Then if we click the return button of the browser (for me, Chrom and Firefox), the content of the form that we filled in is still there.
