This is the documented interface and intentional behavior. dpkg prerm is
invoked before the removal of an *instance* of a package. It can be called
with arguments including (but not limited to): "remove", "deconfigure", and
"upgrade".

You probably don't want to remove config files during the upgrade, and you
should really handle all the cases individually unless you know that they
should be the same.
