[FIX] web_editor: unstuck the UI after an image crop is denied

Steps to produce:
- Drop 'Text - Image' block
- Replace image by illustration
- Try to crop image
- A notification is displayed
- Try saving

The issue is ImageCrop is still not opened and we are trying to wait
for image_cropper_destroyed to trigger, so here we check if ImageCrop
is not opened.
