Steps to reproduce: replacing image stuck issue when deleted

1. Go to Website > Edit.
2. Add any picture snippet (e.g., Text-Image).
3. Click the 'Replace' button and upload an image.
4. Open the media dialog again and delete the uploaded image.
5. Click the 'Discard' button.
6. Try to save the changes.

Issue:

• The website gets stuck in the same position and does not allow saving.
• In the Python terminal, a missing error warning appears because the image is deleted from both ir.ui.view and ir.attachment.

Expected behaviour:

• Saving should be allowed with a default image, that is similar to other images.

This commit catch the warning response and replaces the deleted image, allowing the website to save changes without getting stuck.

Commit [2]: resolve traceback when leaving edit mode via browser

Steps to reproduce:

1. Go to Website > Edit.
2. Open the snippet modal and select any snippet.
3. Press the 'Back' button in your browser.
4. A dialog will appear asking to discard changes; click 'OK'.
5. A traceback error occurs, and an empty space appears in the editor.

Issue:

• Previously, a commit addressed a similar scenario, but that time the browser had an event listener bind on hashchange.
• Now, that hashchange event of browser has been replaced with popstate, which triggers before the 'window' event listener.
• As a result, the editor is left in an unstable state, causing a traceback error.

Solution:

• This commit ensures the 'window' event executes before the browser event.
• It verifies if the editor is open and forces a skipLoad, preventing the route_change call in the browser.
