[UI] Deleting an image having another form changed leads to (useless) confirmation

[mbo-s]

If you edit a company profile and change in one of the forms one value but do not save it and now delete the company picture you will see a notifcation which ask if you would like to stay on the current page or abort. Here it does not matter if you press ok or abort, the image will be removed and the changed value in one of the other forms still are present (unsaved).

Steps to reproduce:

1. Go to https://yawik.org/demo/en/organizations/edit
2. Modify one value, e.g. company name (Do not save)
3. Delete image
