Title: Exam action delete deletes image of exam too

* (fixes #1581)
* This is the ugly version of the fix; the nice version would move the
image deletion logic to the model, then remove the extra
.image.delete() from the various views. That will be a separate
branch.

@jbau - tested on my machine and appears to behave the way one expects.
